MCP server for Dictto – local-first speech recognition and speaker diarization for macOS
npm install dictto-mcpMCP server for Dictto — local-first speech recognition and speaker diarization for macOS.
Connects Claude Code to your running Dictto app, giving Claude access to transcription, speaker diarization, and human-in-the-loop speaker identification tools.
- Dictto macOS app installed and running
- MCP API Server enabled in Dictto: Settings > Privacy > MCP API Server
- Node.js 18+
Add to your Claude Code MCP configuration (~/.claude/claude_code_config.json):
``json`
{
"mcpServers": {
"dictto": {
"command": "npx",
"args": ["-y", "dictto-mcp"]
}
}
}
The MCP server acts as a bridge between Claude Code and Dictto's local API (localhost:8765). All audio processing happens on-device — nothing leaves your Mac.
