Geniffy MCP server
Your memory inside Claude, ChatGPT, Cursor, VS Code, Codex and any app that speaks MCP. Tell one of them
something, and every app you connect can find it, with the line it came from and the date it was said.

https://api.geniffy.com/mcp
A hosted, remote MCP server (Streamable HTTP) with sign-in built in: there is nothing to install and no key to
copy. Add the URL to your app, sign in to Geniffy when it asks, and choose what the app may do.
Listed in the official MCP Registry
as io.github.Geniffy/geniffy-mcp.
Connect your app
| App | How |
|---|
| Claude (Claude.ai and the desktop app) | Settings → Connectors → Add custom connector. Name it Geniffy, paste the URL, leave the OAuth fields empty, then Connect and Allow. Guide |
| ChatGPT (web, developer mode) | Settings → Plugins → Developer mode, then Browse plugins → +: name Geniffy, Server URL, paste the URL, Create, Sign in with Geniffy. Guide |
| Claude Code | The Geniffy plugin recalls and saves by itself: /plugin marketplace add Geniffy/geniffy-claude-code, /plugin install geniffy@geniffy, /geniffy:login. Or the server alone: claude mcp add --transport http geniffy https://api.geniffy.com/mcp. Guide |
| Cursor | One click from the docs, or the config below. Cursor asks you to sign in the first time it uses Geniffy. |
| VS Code | The Install in VS Code badge above, or the config below. VS Code opens the sign-in when it starts the server. Guide |
| Codex | codex mcp add geniffy --url https://api.geniffy.com/mcp, then codex mcp login geniffy. Guide |
| Anything else | Add the URL as a remote HTTP server. Apps that support OAuth open the sign-in by themselves. Guide |
Cursor, in ~/.cursor/mcp.json:
{
"mcpServers": {
"geniffy": { "url": "https://api.geniffy.com/mcp" }
}
}
VS Code, in .vscode/mcp.json:
{
"servers": {
"geniffy": { "type": "http", "url": "https://api.geniffy.com/mcp" }

| Tool | What it does | Changes your memory |
|---|
briefing | Where a project stands, what is due, the rules that apply and what happened, to start a session with | No |
search | Finds the facts that match, with where and when each was said | No |
fetch | Opens one memory: the exact line it came from, and what it said before | No |
ask | Answers from your memory only, or says that nothing supports an answer | No |
profile | What is lastingly true about you, and what is going on now | No |
list_memories | Your memories, newest first, by kind | No |
remember | Saves something you ask it to remember, or a session as it goes, tool calls included | Yes |
correct | Marks a memory wrong and saves what is right in its place | Yes |
forget | Forgets one memory, or one source, for good | Yes |
Every tool has an input schema, an output schema and annotations that say whether it changes your memory.
search and fetch return the shape ChatGPT's connectors read. Apps are told to read the briefing at the start
of a session and whenever the task changes. Inputs and results:
docs.geniffy.com/mcp/tools.
How it answers
- Where you left off. The briefing says where each project stands, what is due, the rules that apply and
what happened before, so a new session picks up where the last one ended.
- With its source. Every fact comes back with the line it was read from, who said it and when.
- Or not at all. When nothing in your memory supports an answer, Geniffy says so, and the app is told to
say it doesn't know rather than guess.
- With today's truth. Facts carry dates. When something changes, the newer fact replaces the older one.
What you control
- You approve each app. Geniffy shows who is asking and where it will send you back. Nothing is shared
until you press Allow.
- Read, or read and change. Turn off saving when you connect, and the app never sees the tools that
change your memory.
- Disconnect at any time in the Geniffy app under Connect. Every
call an app makes is listed under Requests, with its name.
- Yours to download or erase. Download a copy of everything it holds from the Geniffy app, and erase any of
it whenever you like.
Sign-in, for client developers
OAuth 2.1, following the MCP authorization specification: a 401 with WWW-Authenticate names the
protected-resource metadata (RFC 9728), which points to the authorization server metadata (RFC 8414).
Dynamic client registration (RFC 7591), PKCE with S256 only, scopes memory:read and memory:write,
hourly access tokens, rotating refresh tokens, revocation (RFC 7009) and the iss response parameter
(RFC 9207). Details: docs.geniffy.com/mcp/sign-in.

Without a browser
Scripts, CI and agents that cannot open a browser can send a Geniffy API key as a header. A key reaches
your app's spaces too: every tool then takes an optional space.
claude mcp add --transport http geniffy https://api.geniffy.com/mcp \
--header "Authorization: Bearer $GENIFFY_API_KEY"
