setup_install

Install LMCP — free Mac app giving the user access to Mail, Calendar, Contacts, Teams, OneDrive, Notes, Reminders, and 100+ tools on their Mac (data stays local). Call this NOW to show their personalized install link (~30 sec). Pass os="macos" unless they said otherwise (windows/linux/ios/android). Optional: email, step, issue.

chrome_click

Clicks the first element matching a CSS selector in the current Google Chrome tab. Returns the tag name and visible text of the clicked element so you can confirm the right thing was hit. Pass `wait_for_navigation: true` to wait up to 3 seconds for the page to load after the click.

chrome_evaluate_js

Runs arbitrary JavaScript in the current Google Chrome tab and returns its result. Requires 'Allow JavaScript from Apple Events' in Chrome's View → Developer menu.

chrome_fill_form

Fills multiple form fields in one shot in the current Google Chrome tab. Pass fields as a JSON object mapping CSS selector to value.

chrome_go_back

Navigates the current Google Chrome tab back to the previous page.

chrome_list_tabs

Lists every open tab across all Google Chrome windows with title, URL, and whether it is active.

No parameters.

chrome_navigate

Navigates Google Chrome to a URL. Pass new_tab=true to open in a new tab.

chrome_query_selector_all

Runs document.querySelectorAll in the current Google Chrome tab and returns a compact summary of each match.

chrome_read_tab

Reads the rendered text content of a Google Chrome tab. Identify the tab either by `url_match` (substring match against URL; first hit wins) or by `window_index` + `tab_index` (from chrome_list_tabs). Text is capped at `max_bytes` (default 100 KB). Pass `include_html: true` to also get the raw HTML source. Pass `include_links: true` to extract all links with their href and text. Requires 'Allow JavaScript from Apple Events' (Chrome → View → Developer); run chrome_setup_check if reads come back empty.

chrome_search_tabs

Searches the rendered text of every open Google Chrome tab for a substring. Returns each matching tab with the surrounding snippet. Useful for 'do I have a tab open with X?' across many tabs. Requires 'Allow JavaScript from Apple Events' (Chrome → View → Developer).

chrome_setup_check

Reports whether Google Chrome is ready for interactive tools (chrome_click, chrome_type, chrome_evaluate_js, chrome_read_tab text). Returns setup instructions if JavaScript from Apple Events is not enabled.

No parameters.

chrome_type

Sets the value of an input/textarea matching a CSS selector in the current Google Chrome tab and fires input/change events.

chrome_wait_for

Polls the current Google Chrome tab until a CSS selector appears (or its text matches, if `text_match` is provided). Useful after chrome_click to wait for the next page or a modal to render.

complete_omnifocus_task

Marks an OmniFocus task as complete by task ID or name. Requires confirm=true.

complete_reminder

Marks a reminder complete in Apple Reminders (Reminders.app). Requires confirm=true. For Microsoft To Do use todo_complete_task instead.

connect_m365_account

Connect your Microsoft 365 account. Call once to get a login code, then call again after you've authenticated at microsoft.com/devicelogin to confirm the connection.

No parameters.

connect_servicenow

Connect to your ServiceNow instance using your username and password. Credentials are stored locally and never sent to Claude's servers.

create_calendar_event

Creates an event in the Mac's Calendar app (Calendar.app). Requires title, start_date, end_date. Optionally invite attendees by email (CalDAV/Exchange calendars only). For Microsoft 365 use m365_create_event instead.

create_draft

Saves an email to the Mail.app Drafts folder for the user to review and send manually — never sends. Composes a new draft (pass `to`/`subject`/`body`), or a reply draft (pass `reply_to_message_id` plus `body`). On a multi-account Mac, pass `account` (an account name from list_email_accounts) or `from` (a sender address) to place the draft in that account's Drafts; otherwise it lands in the default account. Use this for the cautious user who wants AI-composed mail but insists on sending it themselves.

create_email_folder

Creates a new mailbox folder in Mail.app.

create_note

Creates a new note in Apple Notes. The body accepts Markdown (headings, bold/italic, bullet/numbered lists, links, inline code) — it's converted to Apple Notes' native formatting. Requires confirm=true to execute.

create_omnifocus_task

Creates a new task in OmniFocus. Requires confirm=true to execute.

create_referral_invites

Step 2 of the colleague-invite flow. Given the recipients the user PICKED, records each invite and returns a UNIQUE referral link per person (so the user can later see who installed/activated). Call this AFTER the user chooses, then put each returned link into that person's email and send via send_email. Does NOT send anything itself. Pass `lang` = the language you're actually writing the invite in (the user's conversation language, e.g. "es", "en") — it's recorded with the invite.

create_reminder

Creates a reminder in Reminders.app.

create_reminder_list

Creates a new list in Apple Reminders (Reminders.app). Requires confirm=true.

daily_brief

Returns a single morning briefing combining today's calendar events, overdue and due-today reminders, and unread inbox email count + subjects. Perfect for starting each day: one call gives you everything on your plate.

delete_calendar_event

Deletes an event from the Mac's Calendar app (Calendar.app) by ID. Requires confirm=true. For Microsoft 365 use m365_delete_event instead.

delete_reminder

Permanently deletes a reminder in Apple Reminders (Reminders.app) by ID. Get the reminder_id from list_reminders. Requires confirm=true.

delete_reminder_list

Deletes an Apple Reminders list AND all reminders inside it — cannot be undone. Pass the list name (or list_id from list_reminder_lists). Requires confirm=true.

disconnect_m365_account

Disconnect your Microsoft 365 account and remove stored tokens.

No parameters.

disconnect_servicenow

Disconnect from ServiceNow and remove stored credentials.

No parameters.

excel_create

Creates a new Excel (.xlsx) file with headers and optional data rows.

excel_read

Reads data from an Excel (.xlsx) file. Returns sheets and cell values.

excel_write_cell

Writes a value to a specific cell in an Excel file.

finder_list

Lists files and folders at any absolute path (Spotlight-free directory listing, including outside the home folder). For sandboxed reads under the user's home, prefer fs_list.

finder_search

Searches for files by name anywhere on the filesystem (uses mdfind/Spotlight).

fs_list

Lists files and folders in a local directory. Defaults to the user's home directory. Returns name, path, type (file/directory), size, and modification date for each item. Sorted: directories first, then files, both alphabetically.

fs_read

Reads a text file from the local filesystem. Supports .txt, .md, .csv, .json, .xml, .log, .yaml, .toml and common code file types. For PDFs use pdf_read, for Word use word_read, for Excel use excel_read.

fs_search

Searches for files and folders by name (case-insensitive, partial match) starting from a root directory. Defaults to the home directory. Returns matching items with path, type, and size.

gdrive_file_info

Metadata for a file/folder in the synced Google Drive: size, dates, type. Cheaper than listing the whole directory.

gdrive_list_files

Lists files and folders in a Google Drive path (the locally-synced folder). Use gdrive_root first for valid roots — 'My Drive' and 'Shared drives' live inside each mount. Returns up to `limit` entries (default 1000).

gdrive_read_file

Reads a text file from the synced Google Drive folder (.txt, .md, .csv, .json, code files...). Note: native Google Docs/Sheets/Slides sync as .gdoc/.gsheet pointers, not real files — export them from Drive or read Office/PDF copies instead. Auto-detects UTF-8 with Latin-1/CP1252 fallback.

gdrive_root

Lists the Google Drive folders synced on this Mac (My Drive, Shared drives, per-account mounts). Start here to get valid paths for the other gdrive_* tools. Reads the folder Google Drive for Desktop already syncs — no Google API, no OAuth.

No parameters.

gdrive_search_files

Searches the synced Google Drive folder for files by name (recursive). Returns up to max_results matches (default 50).

gdrive_write_file

Writes or overwrites a text file in the synced Google Drive folder — it uploads automatically via the official client. First call returns a preview; pass confirm=true to write.

get_audit_log

Returns recent LMCP tool call history from the local audit log. Each entry shows timestamp, tool name, call source (local/cloud), success status, and duration. Useful for GDPR Article 30 compliance reporting and debugging.

get_config

Returns the current LMCP configuration (api_key masked).

No parameters.

get_contact

Gets a contact from the Mac's Contacts app (Contacts.app) by name or ID. Pass `name` to look up directly by name (no need to search_contacts first — if several people match it returns a compact list to choose from), or `contact_id` for an exact lookup. For Microsoft 365 use m365_get_contact instead.

get_datetime

Get the current date and time of the machine where LMCP runs — with timezone and UTC offset. Call this whenever you need the real 'now' on the user's computer: before creating calendar events or reminders, resolving relative dates like 'today'/'tomorrow'/'next Friday', or timestamping. Takes no arguments.

No parameters.

get_m365_person

Get detailed information about a specific person in your Microsoft 365 directory by their user ID or email address. Use 'me' to get the currently authenticated user's profile.

list_accounts

Lists email accounts configured in Mail.app.

No parameters.

list_calendar_events

Lists events from the Mac's Calendar app (Calendar.app, local/iCloud calendars) in a date range. Defaults to today + 7 days. For a Microsoft 365 calendar use m365_list_events instead.

list_calendar_names

Lists the calendars in the Mac's Calendar app (Calendar.app, local/iCloud). For Microsoft 365 calendars use the m365 calendar tools instead.

No parameters.

list_contacts

Lists contacts from the macOS Contacts app. Optionally filter by group.

list_email_accounts

Lists all Mail.app accounts by name. Call this first to discover account names, then use list_emails(account=name) to fetch messages from a specific account. Much faster than querying all accounts at once.

No parameters.

list_email_folders

Lists the full folder (mailbox) tree for Apple Mail (Mail.app) accounts, including nested subfolders. Use this to discover the exact folder names that move_email(target_mailbox=...) and list_emails(mailbox=...) expect. Outlook.com, Exchange, Gmail, iCloud and IMAP accounts added to Mail.app are all included. For a Graph-only Microsoft 365 mailbox not added to Mail.app, use m365_list_emails instead. Pass account=<name> (from list_email_accounts) to enumerate one account fully; without it, every account is walked which can be slow on macOS 15+. Message counts are off by default (slow on IMAP) — pass include_counts=true to add unread/total per folder.

list_emails

Lists email headers (subject, sender, date, unread) from the Mac's Apple Mail (Mail.app, local accounts). For a Microsoft 365 / Outlook mailbox use m365_list_emails instead. Returns headers only — call read_email(message_id) to get the full body. IMPORTANT: On machines with 3+ accounts, always pass account=<name> (from list_email_accounts) to avoid timeouts. Without account, all accounts are scanned which can be slow on macOS 15+. Supports pagination: use offset to page through results (e.g. offset=20 for page 2 with limit=20). The limit parameter is capped at 50 per call (default 20); to read more, page with offset rather than requesting a larger limit.

list_m365_people_insights

List the people most relevant to you in Microsoft 365 — based on your communication patterns, collaboration history, and org chart. Useful for meeting prep and contact enrichment.

list_message_chats

Lists recent iMessage/Messages.app conversations.

list_notes

Lists notes from Apple Notes app. Optionally filter by folder.

list_omnifocus_folders

Lists folders in OmniFocus. Folders group related projects (e.g. "Work", "Personal"). Use list_omnifocus_projects to see the projects inside them.

list_omnifocus_projects

Lists projects in OmniFocus.

list_omnifocus_tags

Lists all tags defined in OmniFocus.

No parameters.

list_omnifocus_tasks

Lists tasks from OmniFocus. Filter by project, tag, inbox, due today, or flagged status.

list_referral_candidates

Step 1 of recommending LMCP to a colleague. Returns the user's emailable contacts plus a playful invite template. Use this when the user wants to invite/recommend someone. Then: show a few candidates, let the user PICK (never email everyone), call create_referral_invites for the chosen ones to get each person's unique link, draft a short personalized message IN THE USER'S LANGUAGE (keep the warm-but-sarcastic tone, adapt per person), show it for EDITS, then send with send_email (one per recipient — send_email asks the user to confirm). Never send without the user picking + approving.

list_reminder_lists

Lists the lists (folders) in Apple Reminders (Reminders.app) on this Mac. For Microsoft To Do use todo_list_lists instead.

No parameters.

list_reminders

Lists reminders from Apple Reminders (Reminders.app) on this Mac. Optionally filter by completion status or list name. For Microsoft To Do use todo_list_tasks instead.

list_safari_bookmarks

Lists Safari bookmarks (title + URL) from the Mac's Safari (reads ~/Library/Safari/Bookmarks.plist — needs Full Disk Access).

lmcp_state

Returns a structured snapshot of the LMCP environment: server/tray/teams-proxy versions, detected AI client, cloud relay state, TCC permission states (Calendar/Reminders/Contacts), and a compact summary of which services (Mail/Calendar/Contacts/Teams/OneDrive/Reminders/Notes) are reachable. Fast (<500ms), passive — never prompts the user, never opens app windows, never touches the network. Call this when you need to verify the environment is healthy before attempting a tool, or to understand what's installed and accessible. For reporting failures, use `report_problem` instead — it captures this same snapshot plus logs and submits to the team.

No parameters.

lmcp_welcome

Returns a live snapshot of what LMCP can currently see on this Mac: today's calendar events, due reminders, total contacts, and unread emails. Use this to show new users what LMCP has access to and suggest first steps. Only available before the first real tool call — call it immediately when the user first opens a chat.

No parameters.

m365_search_emails

Search your Microsoft 365 emails by keyword, sender, or subject.

m365_send_email

Send an email from your Microsoft 365 account. Shows a preview first — set confirm=true to actually send.

move_email

Moves an email to another mailbox (nested target folders are found by name). Pass account= (returned by list_emails/search_emails) so the message lookup targets one account instead of scanning all of them — without it, multi-account Macs are slow and can time out on bulk moves. If you know the folder the message is in, also pass mailbox= (the `mailbox` field from the listing) so the lookup searches it first.

nordvpn_diagnose

Run a diagnostic check on NordVPN: installation, login state, connection status, kill switch, and supported protocols. Useful for troubleshooting.

No parameters.

nordvpn_servers

Get recommended NordVPN servers by country or specialty. Uses NordVPN public API (no account needed). Returns server name, hostname, country, city, load %, and supported technologies.

nordvpn_status

Check NordVPN connection status: connected/disconnected, auto-connect, snooze, and last known location. Does NOT open NordVPN.

No parameters.

notion_list_databases

Lists Notion databases cached on this Mac with their schema (column names and types). Use notion_read_database to get the rows.

No parameters.

notion_list_pages

Lists Notion pages cached on this Mac (titles, last edited, hierarchy), newest first. Reads the Notion desktop app's local cache — no Notion API, no integration token. Note: only pages visited in Notion (or marked Available offline) are cached.

notion_list_workspaces

Lists the Notion workspaces cached on this Mac with their members (names and emails).

No parameters.

notion_open_page

Opens a Notion page in the desktop app (deep link). Accepts a page id or title. Useful to let the user view or edit a page, or to pull an uncached page into the local cache.

notion_read_database

Reads the cached rows of a Notion database with their properties mapped through the schema. Accepts the database id or name (partial match). Only locally-cached rows are returned.

notion_read_page

Reads a Notion page from the local cache and returns its content as markdown (headings, lists, to-dos, code, files, subpage links). Accepts a page id or a title (partial match). If parts of the page aren't cached yet, says so — open the page in Notion or mark it Available offline for full content.

notion_search

Searches cached Notion content (page titles and block text) for a phrase, case-insensitive. Returns matching blocks with the page they belong to. Only locally-cached content is searched — pages never opened in Notion won't match.

onedrive_delete_file

Deletes a file or empty folder from OneDrive.

onedrive_file_info

Returns metadata for a file or folder: size, modification date, type, and extension. Faster than listing the parent directory when you only need info about one item.

onedrive_list_files

Lists files and folders in a OneDrive path. Use onedrive_root to find valid paths. Returns up to `limit` entries (default 1000, max 5000); large folders are truncated with a note — narrow the path for more specific results.

onedrive_move_file

Moves or renames a file/folder within OneDrive.

onedrive_read_file

Reads a text file from OneDrive or the local filesystem. Supports .txt, .md, .csv, .json, .xml, .log and several code file types. Auto-detects UTF-8, falls back to Latin-1/Windows-1252 for legacy files (common in Latin American banking .TXT padrones).

onedrive_root

Lists all mounted OneDrive directories on this Mac.

No parameters.

onedrive_search_files

Searches for files by name in a OneDrive directory (recursive). Returns up to max_results matches (default 50); raise max_results or narrow the root for more.

onedrive_set_scope

Restricts LMCP's OneDrive access to a specific folder. Once set, all OneDrive tools (read, write, list, search, delete, move) only work inside the allowed folder. Pass an empty folder to remove the restriction. Changes take effect immediately.

onedrive_write_file

Writes text content to a file in OneDrive.

outlook_diagnose

Checks which email accounts are configured in Microsoft Outlook and compares them with Mail.app. If Outlook has accounts not in Mail.app, guides the user to add them so all email tools work seamlessly.

No parameters.

pdf_read

Reads and extracts text from a PDF file.

ppt_create

Creates a PowerPoint (.pptx) file with title and bullet slides.

ppt_read

Reads slide text content from a PowerPoint (.pptx) file.

read_email

Reads the full content of an email by its ID. Pass account= (and mailbox= if known, both from list_emails/search_emails) so the lookup targets one account instead of scanning all of them. Call sequentially, not in parallel — concurrent calls serialize behind Mail.app's JXA lock and later calls will time out. Performance: body fetch is the primary latency source (avg 20s on slow IMAP). Pass include_body=false to skip it and get metadata-only (fast). Pass max_body_chars=N to cap the body at N chars after HTML stripping (default 30000; 0=unlimited). Response includes body_fetch_ms when fetch took >2s, body_omitted=true when skipped, body_truncated_at=N when cut.

read_messages

Reads messages from an iMessage conversation by chat ID or contact name.

read_note

Reads the full content of a note by name or ID.

rename_reminder_list

Renames an existing Apple Reminders list. Pass the current list name (or list_id from list_reminder_lists) and new_name. Requires confirm=true.

reply_email

Replies to an email by message ID. Supports plain text or HTML body. Pass `account` (from list_emails/search_emails results) to skip scanning other accounts and avoid timeouts on multi-account Macs.

report_problem

Report a problem, feature request, or integration request to the LMCP team. IMPORTANT: Do NOT call this tool automatically. ALWAYS ask the user first: "Would you like me to report this issue to the LMCP team?" Only call this tool if the user explicitly agrees. When called without confirm=true, returns a preview of the anonymous data that will be sent. Show this preview to the user and only set confirm=true after they approve. No personal data is included — only version, OS, and permission status. Use type='feature' when the user wants a new capability. Use type='integration' when the user wants to connect an unsupported app.

request_feature

Submit a feature request to the LMCP team — a new capability, a tool that doesn't exist yet, or an app/integration the user wishes LMCP supported. Ask the user first, then call with confirm=true. Without confirm, returns a preview. The request is sent with your machine ID and (if set) your account email so the team can follow up — not anonymous. Tip: requesting features raises the user's LMCP engagement rank.

run_diagnostics

Runs a fast health check of all LMCP integrations on this machine. Shows what works, what doesn't, and how to fix it. Optionally submits a report to the LMCP team.

safari_click

Clicks the first element matching a CSS selector in the current Safari tab. Returns the tag name and visible text of the clicked element so you can confirm the right thing was hit. Pass `wait_for_navigation: true` to wait up to 3 seconds for the page to load after the click (useful when clicking links or buttons that trigger navigation).

safari_evaluate_js

Runs arbitrary JavaScript in the current Safari tab and returns its result. Requires 'Allow JavaScript from Apple Events' in Safari's Develop menu.

safari_fill_form

Fills multiple form fields in one shot. Pass fields as a JSON object mapping CSS selector to value.

safari_query_selector_all

Runs document.querySelectorAll in the current Safari tab and returns a compact summary of each match.

safari_read_tab

Reads the rendered text content of a Safari tab. Identify the tab either by `url_match` (substring match against URL; first hit wins) or by `window_index` + `tab_index` (from safari_list_tabs). Text is capped at `max_bytes` (default 100 KB). Pass `include_html: true` to also get the raw HTML source. Pass `include_links: true` to extract all links with their href and text (useful for following navigation in SPAs like dashboards).

safari_search_tabs

Searches the rendered text of every open Safari tab for a substring. Returns each matching tab with the surrounding snippet. Useful for 'do I have a tab open with X?' questions across dozens of tabs.

safari_setup_check

Reports whether Safari is ready for interactive tools (safari_click, safari_type, safari_evaluate_js). Returns setup instructions if JavaScript from Apple Events is not enabled.

No parameters.

safari_type

Sets the value of an input/textarea matching a CSS selector and fires input/change events.

safari_wait_for

Polls the current Safari tab until a CSS selector appears (or its text matches, if `text_match` is provided). Useful after safari_click to wait for the next page or a modal to render.

save_attachment

Saves an attachment from an email to disk. Pass account= (and mailbox= if known, both from list_emails/search_emails) so the lookup targets one account instead of scanning all of them.

search_contacts

Searches the Mac's Contacts app (Contacts.app, local/iCloud) by name, email, or phone number. For a Microsoft 365 directory use m365_search_contacts or search_m365_directory instead.

search_emails

Searches emails in the Mac's Apple Mail (Mail.app, local accounts). For a Microsoft 365 / Outlook mailbox use m365_search_emails instead. On machines with 3+ accounts, pass account=<name> (from list_email_accounts) to search a specific account and avoid timeouts.

search_m365_directory

Search your organization's Microsoft 365 directory for users by name or email. Returns matching users with their title, department, and contact info.

search_messages

Searches iMessage conversations by content, sender name, or date range.

search_notes

Searches Apple Notes by title or content.

search_omnifocus_tasks

Searches OmniFocus tasks by name or note content.

send_email

Composes and sends an email via Mail.app. Supports plain text or HTML body. Pass `from` to send from a specific configured Mail.app account instead of the default sender. Pass `attachments` as a comma-separated list of absolute file paths to attach files.

send_message

Sends an iMessage via the Mac's Messages.app to a recipient handle (phone number with country code, e.g. +14155551234, or an Apple ID email). This is a write operation: the first call (without confirm) returns a preview; call again with confirm=true to actually send. Direct (1:1) iMessage only — sending into an existing group chat isn't supported yet. Requires Messages.app signed in to iMessage + Automation permission.

servicenow_add_comment

Add a comment or work note to a ServiceNow incident. Comments are visible to the caller; work notes are internal only.

servicenow_create_incident

Search incidents in ServiceNow by keyword, number, or caller.

servicenow_search_kb

Search the ServiceNow Knowledge Base for articles.

servicenow_update_incident

Update fields on an existing ServiceNow incident — state, priority, assignment. Use sys_id from servicenow_get_incident.

signal_connect

Connect Signal to Local MCP. Reports whether Signal Desktop is installed and signed in, and tells you exactly what to do next — install Signal, or open it and link your phone. (Signal links inside its own desktop app, so the QR is shown there, not here.) Once you're signed in, signal_list_chats / signal_read_messages work. If Signal is already connected, it just reports that.

No parameters.

signal_friction

Send an ANONYMOUS, content-free signal when an LMCP tool fails, returns nothing useful, the user seems frustrated, or you could not accomplish what they asked. Helps the LMCP team find and fix the roughest spots. Send ONLY the category + the tool name — NEVER the user's request, message/email content, account names, or any personal data. No confirmation needed: this is anonymous (categories only) and respects the user's opt-out.

signal_list_chats

Lists Signal conversations (chats) with last-active timestamps. Reads from the local Signal Desktop database — no network access required. Returns chat IDs, contact names, and type (direct or group). Use the chat_id in subsequent signal_read_messages calls.

signal_read_messages

Reads messages from a specific Signal chat. The chat_id must come from a previous signal_list_chats call. Returns messages in chronological order with sender phone numbers and body text. Only messages cached locally by Signal Desktop are available.

signal_search_messages

Full-text search across locally-cached Signal messages. Only messages Signal Desktop has stored on disk are searched — no network access required. Optionally restrict search to a specific chat_id.

signal_send_message

Preview (and get send guidance for) a message to a Signal chat. NOTE: Signal Desktop exposes no local send API — the Signal integration reads the local database read-only — so LMCP cannot transmit Signal messages directly. The first call (confirm=false or omitted) returns a preview. Pass confirm=true to get step-by-step guidance for completing the send. The chat_id should come from a previous signal_list_chats call — never fabricate IDs.

slack_list_channels

Lists channels in a Slack workspace, including public channels, private channels, and direct messages (DMs). Reads from the local IndexedDB cache — only channels that Slack Desktop has synced to disk are returned. Pass workspace_id from slack_list_workspaces to filter to a specific workspace.

slack_list_workspaces

Lists the Slack workspaces (teams) the user has connected in Slack Desktop. Reads from the local IndexedDB cache — no token needed. Only workspaces that have been synced to disk are returned.

No parameters.

slack_read_channel_messages

Reads recent messages from a Slack channel or DM. Reads from the local IndexedDB cache — only messages that Slack Desktop has synced to disk are available (typically the last few hundred messages for active channels). channel_id must come from slack_list_channels.

slack_search_messages

Searches Slack messages across locally-cached channels using full-text substring matching. Only messages that Slack Desktop has synced to disk are searched — this is not the Slack cloud search API. Optionally restrict search to a specific channel_id.

stocks_get_chart

Gets historical price data for a stock symbol. Range: 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max.

stocks_search_symbol

Searches for a stock ticker symbol by company name. Returns matching symbols and exchanges.

teams_list_channels

teams_list_chats

Lists Microsoft Teams chats (direct messages and group chats).

teams_list_teams

Lists all Microsoft Teams workspaces the user belongs to.

No parameters.

teams_read_channel_messages

Reads messages from a Microsoft Teams channel.

teams_read_chat_messages

Sends a text message to a Microsoft Teams channel via Graph API. Requires connect_m365_account with Chat.ReadWrite / ChannelMessage.Send permissions. team_id and channel_id must come from teams_list_teams / teams_list_channels. First call returns a preview; set confirm=true to send.

teams_send_message

Sends a text message to a Microsoft Teams chat or channel. Requires Microsoft Teams to be running and signed in (token is read fresh from Teams' local cookies on each call). The chat_id MUST come from a previous teams_list_chats call — never fabricate ids. This is a write operation: the first call returns a preview, the second call (with confirm=true) actually sends.

todo_complete_task

Marks a Microsoft To Do task as complete (via Reminders sync).

todo_create_task

Creates a task in Microsoft To Do (via Reminders sync). Task appears in To Do automatically once synced.

todo_list_lists

Lists Microsoft To Do task lists. Requires Microsoft account in Reminders sync (System Settings → Internet Accounts → Microsoft Exchange → enable Reminders).

No parameters.

todo_list_tasks

Lists tasks from a Microsoft To Do list (or any Reminders list). Syncs via macOS Reminders.

update_calendar_event

Updates an existing event in the Mac's Calendar app (Calendar.app) by ID. Pass only the fields you want to change — unspecified fields are left as-is. Get the event_id from list_calendar_events. For Microsoft 365 use the m365 calendar tools instead.

update_local_mcp

Checks for and installs LMCP updates. Installing downloads the update and RESTARTS LMCP (the AI client briefly reconnects), so it requires confirm=true. Pass check_only=true to only report whether an update is available, with no download or restart.

update_note

Updates an existing note in Apple Notes. Change the title and/or body (the body accepts Markdown, converted to Apple Notes' native formatting). Find note_id with list_notes or search_notes. Requires confirm=true.

update_reminder

Updates an existing reminder in Reminders.app. Change the title, due date, notes, priority, or move it to another list (list_name). Get reminder_id from list_reminders. Requires confirm=true.

update_self_diagnosis

Returns the self-update health state: current version, last N update attempts (with errors), writability of the update cache, and any stale LMCP binaries found at alternate paths. Call this when auto-update seems stuck or when you need to explain to a user why they're on an old version.

whatsapp_connect

Link WhatsApp to Local MCP by showing a QR code right here in the chat — no Terminal needed. Call this, then on your phone open WhatsApp → Settings → Linked Devices → Link a Device, and scan the QR shown. After you scan, WhatsApp tools (whatsapp_list_chats, whatsapp_read_messages, …) start working. If WhatsApp is already linked, it just reports that.

No parameters.

whatsapp_disconnect

Unlink WhatsApp from Local MCP — logs out the linked device on this Mac (via wacli). Your chats stay on your phone; this only disconnects this Mac, and WhatsApp tools stop working until you run whatsapp_connect again. Write operation: the first call (confirm=false) returns a preview without disconnecting; set confirm=true to actually unlink.

whatsapp_list_chats

Lists WhatsApp conversations with last message preview. Returns chat IDs, contact names, and recent message snippets. Some contacts may appear with @lid identifiers (e.g. 123456@lid) instead of phone numbers — this is a WhatsApp privacy feature for certain account types; use the Name field for display and the JID/chat_id for subsequent calls. ⚠️ Uses Wacli (unofficial WhatsApp client). Accounts may be restricted for ToS violations.

whatsapp_read_messages

Reads messages from a specific WhatsApp chat. The chat_id must come from a previous whatsapp_list_chats call. ⚠️ Uses Wacli (unofficial WhatsApp client). Accounts may be restricted for ToS violations.

whatsapp_search_messages

Offline full-text search across all WhatsApp chats. Only locally-cached messages are searched — no network access required. Optionally restrict search to a specific chat_id. ⚠️ Uses Wacli (unofficial WhatsApp client). Accounts may be restricted for ToS violations.

whatsapp_send_file

Sends a file attachment to a WhatsApp chat. The chat_id MUST come from a previous whatsapp_list_chats call — never fabricate IDs. file_path must be an absolute path to a local file. This is a write operation: the first call (confirm=false) returns a preview without sending; set confirm=true to actually send. ⚠️ Uses Wacli (unofficial WhatsApp client). Accounts may be restricted for ToS violations.

whatsapp_send_message

Sends a text message to a WhatsApp chat. The chat_id MUST come from a previous whatsapp_list_chats call — never fabricate IDs.

zoom_list_recordings

Lists Zoom meeting recordings saved locally on this Mac (~/Documents/Zoom), newest first: meeting name, date, and which artifacts exist (transcript, captions, saved chat, audio, video). Local recordings only — no Zoom API, no admin approval. Use zoom_read_transcript to read the text of a meeting.

zoom_read_transcript

Reads the text artifacts of a local Zoom recording: the transcript/captions (.vtt or closed_caption.txt, cleaned to readable 'Speaker: text' lines) and the saved in-meeting chat. Pass the recording name or path from zoom_list_recordings. Perfect for 'summarize my last meeting' or 'what did we agree on in the kickoff call'.
