@beacio/mcp
MCP server that teaches coding agents (Claude, Cursor, Copilot, …) how to ship iOS Safari Web Bluetooth with beacio.
Eleven tools (seven consumer + four developer), all offline, all citing canonical docs at https://beacio.com/docs-md/*.
Install
Run via npx — no install step needed:
Or add it to your MCP client config (example: Claude Desktop, ~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"beacio": {
"command": "npx",
"args": ["-y", "@beacio/mcp"],
"env": { "MCP_CLIENT": "claude-desktop" }
}
}
}
beacio scaffolding CLI
This package also ships the unscoped beacio CLI (formerly the standalone @beacio/cli) alongside the MCP server. It scaffolds and verifies beacio integration in a web project:
npx beacio init
npx beacio migrate
npx beacio check
beacio migrate applies the same three edits the beacio_patch_existing_app MCP tool emits (single-sourced from one transform).
Available in the default (consumer) mode for agents shipping the SDK into an app.
| Tool | Purpose |
|---|
beacio_install_plan | Canonical install steps + runnable snippet for html | react | vue | svelte | angular | next × npm | pnpm | yarn | bun | cdn. |
beacio_patch_existing_app | Brownfield: concrete FileEdits to add iOS Safari support to an EXISTING Web Bluetooth app — bootstrap into <head> before the first navigator.bluetooth read, optionalServices onto the iOS requestDevice branch, and the "use Bluefy / Web BLE browser" message swapped for the install/enable affordance. |
beacio_verify_integration | Agent-runnable checklist (shell commands + pass criteria) confirming the polyfill is installed, bootstrapped, builds, and resolves types — plus a brownfield mode for an already-written app. |
beacio_example | Ready-to-paste code for a BLE profile: heart-rate, battery, cgm, lock, beacon, peripheral-chat. |
beacio_detect_ios_support | Runtime detection snippet for navigator.bluetooth + window.beacioIOS, with every gotcha noted. |
beacio_premium_guide | One of the iOS-only premium surfaces: backgroundSync, notifications, liveActivity, beacons, peripheral, whiteLabel. |
beacio_troubleshoot | Diagnostic checklist + common fix for extension-not-detected, device-disconnects, gatt-operation-failed, notifications-not-firing. |
beacio_spec_citation | W3C Web Bluetooth spec URL + summary + caveats for a given method (e.g. navigator.bluetooth.requestDevice). |
Surfaced with --developer mode, for agents working inside the beacio monorepo itself.
| Tool | Purpose |
|---|
beacio_dev_best_practices | Read the project's AGENTS.md best-practices guide, optionally filtered by topic section. |
beacio_dev_search_docs | Search the beacio documentation index by keyword; returns ranked results with beacio.com URLs. |
beacio_dev_list_structure | Build a tree view of the monorepo directory structure (optional root path, depth 1-4, gitignore support). |
beacio_dev_find_examples | Search a curated index of key source files; returns ranked matches with file path, line number, and category. |
Every response is JSON with a source_url that points into https://beacio.com/docs-md/ so agents can cite authoritative docs.
Attribution token
beacio_install_plan returns an attribution_token of the form:
beacio_YYYYMM_mcp_<8..16 chars a–z0–9>
Example: beacio_202604_mcp_3p9xq2k8m4r
This token is accepted by the beacio beacon endpoint so installs originating from this MCP server are attributable. Share the token with the user unchanged — do not modify, truncate, or regenerate it.
Telemetry
Each tool call POSTs a minimal event to https://mcp-telemetry.beacio.com/mcp-telemetry (telemetry is enabled by default):
{
"tool": "beacio_install_plan",
"client_name": "claude-desktop",
"client_version": "1.2.3",
"success": true,
"duration_ms": 42,
"attribution_token": "beacio_202604_mcp_3p9xq2k8m4r"
}
No device data, no BLE payloads, no user input is ever sent. Fire-and-forget, 1-second timeout.
Opt out: telemetry is on by default; disable it by setting BEACIO_MCP_TELEMETRY to 0, false, off, or no (case-insensitive), or by setting the cross-tool DO_NOT_TRACK=1.
Identify your client: set MCP_CLIENT (e.g. claude-desktop, cursor, copilot-cli). Defaults to an empty string. Optionally set MCP_CLIENT_VERSION (defaults to empty string).
