What the publisher says

From the Crixin Voice repository's README, as published. We do not edit it. Read it on GitHub

crixin

The MCP toolkit for AI agents. Two MCPs in one npm package, sharing one local SQLite, installing into the same MCP-aware hosts you already use.

  • Voice MCP — give your AI a phone line. Real outbound calls + SMS + transcription through your own Twilio.
  • Coder MCP — give your AI a memory. Reads back every Claude Code, Codex CLI, and Cursor session you've ever had.

Local-first. Bring your own Twilio. Bring your own LLM. No SaaS in the middle.

Install

npm i -g crixin
crixin install                # writes BOTH MCPs (voice + coder) into Claude Desktop, Claude Code, Cursor, Codex CLI

Escape hatches if you want one half only:

crixin voice install          # only the phone half
crixin coder install          # only the memory half

For Voice MCP, set Twilio creds in the env your AI host launches from:

export TWILIO_ACCOUNT_SID=ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
export TWILIO_AUTH_TOKEN=your_auth_token
export TWILIO_PHONE_NUMBER=+15555550100
export DEEPGRAM_API_KEY=...   # optional — needed for Voice Wrapped + Caller Archetype

Platform mode (no Twilio account needed)

Don't want to bring your own Twilio? Grab an API key from the Crixin dashboard and set it instead — all six voice tools route through Crixin's hosted platform:

CRIXIN_API_KEY=crx_live_... npx -y crixin voice mcp

No TWILIO vars, no DEEPGRAMAPIKEY (transcription runs server-side). CRIXINAPI_BASE overrides the API origin if you need to. The geo-gate still runs locally — strict-consent destinations (US/UK/EU/AU) require consented: true either way.

Verify before you dial:

crixin voice doctor           # BYO: one GET against Twilio. Platform mode: checks your key + minute quota. No charges.

For Coder MCP, ingest your AI coding history:

crixin coder ingest           # pulls Claude Code, Codex CLI, Cursor sessions → ~/.crixin/crixin.db

Remote MCP (nothing to install)

The same six voice tools are served over Streamable HTTP by the hosted platform. Point any MCP host at the endpoint with your crxlive… key:

claude mcp add --transport http crixin-voice https://crixin-platform.vercel.app/api/mcp \
  --header "Authorization: Bearer crx_live_..."

Cursor / VS Code: add an HTTP MCP server with the same URL and Authorization header. ChatGPT: Settings → Connectors → Developer mode → add the URL. The endpoint is stateless (POST only); tool names, arguments and results are identical to the local server.
