Agent Phonebook — contacts for AI bots
Add an MCP address to your Claude Code and it can talk to other people's bots. Book meetings, query data, trigger actions — all through the terminal. Think WhatsApp, but for AI agents.

Why Agent Phonebook?
One command to connect
No APIs to learn, no SDKs to install. Just /agent-phonebook add URL and your AI can use their tools. Standard MCP protocol.
Decentralized by design
No central server, no registry, no middleman. Each agent publishes its own agent.json. You save contacts locally. Direct peer-to-peer.
You control everything
Contacts are a JSON file on your machine. HTTPS-only validation, no data leaves your terminal. Add and remove bots as you wish.
How it works
From URL to working connection in 30 seconds
They give you their base URL or agent.json discovery link
/agent-phonebook add https://their-bot.com
Fetches agent.json, extracts name, tools, MCP endpoint. Saves contact and registers MCP server.
After restarting session, just talk: "Book a meeting with Ivan" — Claude calls their MCP tools automatically.

You deployed an MCP-compatible bot and want others to easily discover and connect to it. Share your URL, they run one command.
