windy-word-mcp

An MCP (Model Context Protocol) server that turns Windy Word — the voice-to-text desktop app — into an agent-controllable platform. 115 tools spanning paste / hotkeys / transcription / recording verbs / audio devices / install / diagnostics / archive / voice clones / translation / documents / system / window / account + billing / TTS / settings-undo / music-ducking / bulk-clone-ingest / soul-file export.

Windy Word ships a local HTTP control server on 127.0.0.1:18765. This package is a schema-validated MCP wrapper around it. Agents call MCP tools; the server forwards to Windy Word over localhost; everything happens on the user's machine (no network round-trips for state queries).

npm mcp registry

Install

For most users:

claude mcp add windy-word --command "npx" --args "-y" "windy-word-mcp"

Or in ~/.claude.json / ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "windy-word": {
      "command": "npx",
      "args": ["-y", "windy-word-mcp"]
    }
  }
}

Local-dev (cloned repo):

git clone https://github.com/sneakyfree/windy-word-mcp && cd windy-word-mcp
npm install
claude mcp add windy-word --command "node" --args "$(pwd)/bin/windy-word-mcp.js"

Requirements

Node.js ≥ 18
Windy Word running locally (Electron app — the HTTP control server binds automatically at startup)

Environment overrides

Variable	Default	Purpose
`WINDY_WORD_MCP_HOST`	`127.0.0.1`	Override the control-server host
`WINDY_WORD_MCP_PORT`	`18765`	Override the control-server port
`WINDY_WORD_MCP_TIMEOUT_MS`	`5000`	Default per-request timeout (the install + transcribe tools override this internally for long ops)

Tool catalog (115 tools, 22 categories)

Regenerate this section's tool count any time with npm run test:list-tools (node scripts/list-tools.js), which enumerates the live server's registered tools.

Platform (1)

Tool	What it does
`get_platform`	OS, arch, distro, display server, desktop env, xdotool/ydotool presence

Paste strategies (9)

12 platform-specific paste backends (macOS / Windows / Linux X11 / Linux Wayland) with capability metadata, hotkey-collision auto-detection, and a verified fallback chain.

Tool	What it does
`list_paste_strategies`	All 12 strategies + per-strategy availability + resolved chain + collision flag
`get_active_paste_strategy`	Current selection + resolved chain
`set_paste_strategy`	Switch active (or `"auto"`)
`test_paste_strategy`	Fire a specific strategy at the focused window (injects text!)
`auto_paste`	Run the auto-execute chain with explicit candidates
`run_paste_injection_test`	Real end-to-end test — spawns Tk target, fires paste, diffs result
`get_paste_history` / `clear_paste_history`	In-memory audit log
`get_paste_target`	XWayland vs Wayland-native detection

Hotkeys (3)

Tool	What it does
`list_hotkeys`	Current bindings + available actions + reserved combos
`set_hotkey`	Rebind a global shortcut (Electron accelerator format)
`reset_hotkeys`	Restore all global shortcuts to catalog defaults + re-register

Transcription engine (3)

Tool	What it does
`list_models`	Whisper model catalog + current + WindyTune ladder

Recording verbs (8)

Tool	What it does
`start_recording`	Begin a mode-aware recording (batch / streaming / API engine)
`stop_recording`	End the recording → trigger transcription + paste pipeline
`cancel_recording`	Abort an in-flight recording without saving

`install_dependency` family (8)

Agent installs missing system tools (Linux/macOS/Windows package managers). Linux uses pkexec; macOS uses user-scope brew; Windows uses winget. Whitelist-only: wtype, ydotool, wl-clipboard, xdotool, cliclick, ffmpeg.

Coverage

115 MCP tools now surface the Windy Word desktop app's agent-control surface — paste, hotkeys, transcription, recording verbs, audio devices, install/Doctor, archive, voice clones (Phase 1 + Phase 2 cloud training), translation, documents, sound effects, window + app lifecycle, account + billing, TTS, settings-undo, music-ducking, bulk-clone-ingest, and soul-file export. Internal renderer events that are not agent-callable RPCs by design are intentionally excluded.

Quality bar

scripts/stress-test.js exercises every safe tool, including:

Whitelist rejection at the MCP zod layer
Structured 4xx error pass-through for validation failures
Cross-OS rejection (cliclick on Linux, wtype on macOS)
Real paste injection round-trip (Tk capture + diff)
Concurrency burst (20 parallel get_platform calls)
Idempotent installs (alreadyInstalled detection)

67/67 passing at v1.0.0 release.

Known intermittent: run_paste_injection_test ~1-in-5 hits a Mutter focus-handoff race on Wayland+GNOME. Re-run is clean. Not a regression.

Sibling components

These are private repositories — the names are here so the architecture reads clearly, not as links.

windy-pro — the Electron app (Windy Word). Contains the control server, settings catalog, install registry, Doctor checks, paste strategies, archive scanner, voice-clone CRUD.
windy-fix-me — the cloud-relay Cloudflare Worker. Receives Doctor findings + platform context, returns LLM-augmented remediation.

This server is the public, supported interface to Windy Word. You do not need either of the above to use it — install from npm as shown at the top.
