Works with Claude, with some setup first
You need a Crixin Voice key (create it on the maker’s site) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone
Let AI install it
Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.
Please install the MCP server Crixin Voice for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "voice": { "command": "npx", "args": [ "-y", "crixin", "voice", "mcp" ], "env": { "CRIXIN_API_KEY": "your-value", "TWILIO_AUTH_TOKEN": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For CRIXIN_API_KEY, TWILIO_AUTH_TOKEN, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Crixin Voice tools really show up.This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.
Install Node.js (if you don’t have it)
Already installed? Check first · Open Terminal, type this command and press Enter
node -v- A version number such as v26.13.1 = installed, skip this step

Common questions
Is Crixin Voice safe?
It passed 2 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization, CRIXIN_API_KEY, TWILIO_AUTH_TOKEN
Does it run on my computer or in the cloud?
Either way works: install it on your computer or connect to the cloud version.
Is it still maintained?
The GitHub repo last changed 42 days ago, and the latest version (0.7.2) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?

README from the maker
Open the README
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
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 crixincrixin 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 halfcrixin coder install # only the memory half
For Voice MCP, set Twilio creds in the env your AI host launches from:
export TWILIO_ACCOUNT_SID=ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxexport 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 mcpNo TWILIO_* vars, no DEEPGRAM_API_KEY (transcription runs server-side). CRIXIN_API_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.dbRemote 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 crx_live_… 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.
What each MCP exposes
Voice MCP — crixin-voice
| Tool | What it does |

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. |

Stack
- STT: Deepgram Nova-2 (optional —
DEEPGRAM_API_KEY). - TTS: Twilio Polly + Google neural voices via TwiML
- 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. |
| Crixin Unlimited | $9.99/mo | Hosted calling with no Twilio account: unlimited calls, one monthly fee. Premium voice for the first 60 minutes each month, then standard, then basic — the call always gets made. One call at a time per account. Platform mode (CRIXIN_API_KEY) and the remote MCP run on this plan. |
Existing Coder Pro ($5/mo: hosted Wrapped + crixin sync) keeps working and is being folded into Unlimited.
Privacy posture
- Zero servers between you and Twilio. Calls hit
api.twilio.comdirectly with your auth header. - Coder MCP reads JSONLs your AI host already wrote to your disk. Nothing leaves your machine.

- Local mode (BYO Twilio): this package collects nothing. Calls go straight to Twilio with your credentials; call history and transcripts live in
~/.crixin/crixin.dbon your machine. Your AI host sees tool results the same way it sees any other tool. - Hosted mode (`CRIXIN_API_KEY` or the remote MCP): the Crixin platform stores call metadata (numbers, timestamps, duration, status), recordings and transcripts you request, and usage counters for billing. Calls are carried by Twilio; transcription runs on Deepgram; hosted voice calls use OpenAI, Deepgram and ElevenLabs models. We do not sell data.
- Retention: account data while the account is active, deleted within 30 days of account deletion; recordings and transcripts deleted with the account; payment records as required by law.
- Contact: privacy@crixin.com (privacy requests) · help@crixin.com (support).
- 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.
