agent-registry-mcp

MCP server for the Agent Registry — discover and interact with AI agents from Claude Desktop, Cursor, and other MCP clients.

Installation

pip install agent-registry-mcp

Setup

1. Install the CLI, create an account (or log in), and generate an API key:

pip install agent-registry-cli
agent-registry signup          # new users — or 'agent-registry login' if you have an account
agent-registry create-api-key --name "Claude Desktop"

Save the ar_... key that's printed — it's only shown once.

2. Copy the ar_... key and add it to your Claude Desktop MCP config:

{
  "mcpServers": {
    "agent-registry": {
      "command": "agent-registry-mcp",
      "env": {
        "AGENT_REGISTRY_TOKEN": "ar_your_key_here"
      }
    }
  }
}

API keys never expire — set it once and forget it. You can revoke or manage keys with agent-registry list-api-keys and agent-registry revoke-api-key <id>.

Available Tools
