v0.4.0 · live on npm

Give your AI a phone and a memory.

Your AI agent can call real numbers, send SMS, transcribe conversations, and recall context from every coding session it's had with you. Locally, through your own Twilio and your own machine. Works with Claude Code, Cursor, Codex CLI, and Claude Desktop. Built on MCP.

What it does

Two new senses. One toolkit.

Crixin gives your AI agent the two things a chat window doesn't: a way to reach the world, and a way to remember what it did there. Both ship in one npm package, share one local SQLite, and install into Claude Code, Cursor, Codex CLI, and Claude Desktop with a single command.

01

The phone

Your AI dials real numbers, sends SMS, and transcribes the call — through your own Twilio account. Polly + Google neural voices in 30+ languages including Egyptian Arabic. Compliance gates (TCPA windows, geo-gate, DNC) baked in.

02

The memory

Your AI recalls every Claude Code, Codex CLI, and Cursor session you've ever had with it. No more re-explaining your project for the 40th time — the LLM driving today's call can pull up what you and it agreed on last Tuesday at 3am.

The year-end receipt

Wrapped. For both halves.

crixin voice wrapped and crixin coder wrapped each emit a self-contained HTML report — heatmaps, archetypes, top destinations or top projects, monthly bars. Local. Shareable as a screenshot. PII auto-stripped. The proof your data layer is doing its job.

A Crixin Wrapped report — heatmap of activity, archetype reveal, top destinations or top projects, monthly bars, estimated cost

How it works

One install. Two new abilities.

No setup wizard. No SaaS account. No telemetry. The npm package is the entire product. One command wires Crixin into Claude Code, Cursor, Codex CLI, and Claude Desktop — your AI host picks up the new abilities on next launch.

# Install + wire Crixin into your AI hosts.
$ npm i -g crixin && crixin install

# Ingest your existing AI coding history into local SQLite.
$ crixin coder ingest

# Verify Twilio reachable (no charges — just an account fetch).
$ crixin voice doctor

# Place a real call from the CLI, or ask your AI in chat.
$ crixin voice call +201500309524 "Hi from Crixin."

# Or ask your AI: "find when we last discussed the auth bug."

Per-host install

Pick a host. One click.

crixin install handles every supported host at once. If you'd rather drop one entry by hand, the blocks below register the phone half — swap "voice" for "coder" to register the memory half instead.

Cursor

Drop the block into ~/.cursor/mcp.json. Cursor picks it up on restart.

{
  "mcpServers": {
    "crixin-voice": {
      "command": "npx",
      "args": ["-y", "crixin", "voice", "mcp"]
    }
  }
}
Copy block

Claude Code

One CLI command. Lands in ~/.claude.json alongside any existing MCP servers.

claude mcp add crixin-voice -- npx -y crixin voice mcp
Copy command

Codex CLI

Append this block to ~/.codex/config.toml. Codex picks it up on next launch.

[mcp_servers.crixin-voice]
command = "npx"
args = ["-y", "crixin", "voice", "mcp"]
Copy block

Pricing
