crixin

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=[phone]
export DEEPGRAM_API_KEY=...   # optional — needed for Voice Wrapped + Caller Archetype

Verify before you dial:

crixin voice doctor           # one GET against Twilio. No charges, instant feedback on stale tokens.

For Coder MCP, ingest your AI coding history:

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

What each MCP exposes

Voice MCP — crixin-voice

Tool	What it does
make_call	Outbound voice call. to + prompt (assistant speaks it; recipient response recorded), or raw TwiML.

list_calls	Recent calls — filter by to / from / status / start_time_after.
list_recordings	Recordings + auth-protected media URLs for a Call SID.
transcribe_call	Run a recording through Deepgram. 30+ languages including Arabic.
send_sms	SMS / MMS through Twilio. Messaging Service support.

Coder MCP — crixin-coder

Tool	What it does
search_sessions	Full-text search across every ingested Claude Code / Codex / Cursor session.
list_recent_sessions	Newest sessions first, with project + token counts.
get_session	Pull a full session transcript by ID.
stats	Aggregate counts across the local SQLite store.

Everyday commands

# Voice MCP
crixin voice doctor                # live-probe Twilio (no charges)
crixin voice call <to> [prompt]    # one-off call from the CLI
crixin voice sms  <to> <body>      # one-off SMS
crixin voice ingest                # pull recent Twilio calls + Deepgram transcripts → local SQLite
crixin voice wrapped --year 2026   # annual recap (HTML) — heatmaps, archetype, top destinations
crixin voice archetype             # caller archetype reveal (Quick Pitcher / Patient Listener / …)
crixin voice mcp                   # run as a stdio MCP server (used by AI hosts via npx)

# Coder MCP
crixin coder ingest                # ingest AI coding sessions → ~/.crixin/crixin.db
crixin coder search <query>        # CLI search across sessions
crixin coder dashboard             # local Hono dashboard on 127.0.0.1
crixin coder wrapped --year 2026   # annual recap (HTML) — top projects, monthly bars, archetype
crixin coder archetype             # 11 archetypes — 5 for you, 6 for your AI
crixin coder mcp                   # run as a stdio MCP server (used by AI hosts via npx)

Per-host install (manual)

# Claude Code
claude mcp add crixin-voice -- npx -y crixin voice mcp
claude mcp add crixin-coder -- npx -y crixin coder mcp

# Cursor — append to ~/.cursor/mcp.json
{
  "mcpServers": {
    "crixin-voice": { "command": "npx", "args": ["-y","crixin","voice","mcp"] },
    "crixin-coder": { "command": "npx", "args": ["-y","crixin","coder","mcp"] }
  }
}

# Codex CLI — append to ~/.codex/config.toml
[mcp_servers.crixin-voice]
command = "npx"
args = ["-y","crixin","voice","mcp"]

[mcp_servers.crixin-coder]
command = "npx"
args = ["-y","crixin","coder","mcp"]

Or just run crixin install and let it wire everything for you.

Wrapped (the year-end receipt)

Both halves emit a self-contained HTML report.

crixin voice wrapped               # → ./crixin-voice-wrapped-2026.html
crixin coder wrapped               # → ./crixin-coder-wrapped-2026.html

Hour-of-day heatmaps, monthly bars, archetype reveal (Patient Listener / Hard Closer / Ducker / Cowboy / Architect / …), top destinations or top projects, top languages or top models. PII-stripped. Shareable as a screenshot. No upload.

Stack

• STT: Deepgram Nova-2 (optional — DEEPGRAM_API_KEY).
• TTS: Twilio Polly + Google neural voices via TwiML <Say>. (Polly.Joanna-Neural for en-US, Polly.Hala-Neural for ar-EG, Polly.Lucia-Neural for es-ES, etc.)
• LLM: none in the open-source call path — your AI host decides what to say. Pro tier can plug in hosted Wrapped + memory sync.
• Storage: local SQLite at ~/.crixin/crixin.db. Tables: voice_calls, voice_recordings, sessions, messages.

Pricing

Tier	Price	What you get
Open Source	Free forever	Both MCPs, all tools, all Wrapped, all archetypes. MIT-licensed. Bring your own Twilio.
Pro	$5/mo	Hosted Wrapped (shareable URL), cross-machine memory sync, premium archetypes. 3-day free trial.

See full pricing.

Privacy posture

• Zero servers between you and Twilio. Calls hit api.twilio.com directly with your auth header.
• Coder MCP reads JSONLs your AI host already wrote to your disk. Nothing leaves your machine.
• Transcripts and call recordings stay in your Twilio account and your local SQLite.
• No telemetry. No upload. No analytics pixels.

Geo-gate (Voice MCP)

Outbound calls to strict-consent jurisdictions (US, Canada, UK, IE, FR, ES, IT, NL, AU, NZ) require an explicit --consented flag or consented: true in the MCP tool args. Permissive jurisdictions (Egypt, UAE, KSA, Jordan, Kuwait, Qatar, Bahrain, Oman, Lebanon, Nigeria, ZA) dial without the flag. Germany is blocked outright. Override with CRIXIN_VOICE_ALLOWED_CC.
