Find an agent by what it does
Filed by addrbook from the words in each listing, so a heading says what a listing claims to be for. Each heading shows one row per provider, those that answered their last check first.
Nothing has been filed yet. Listings are filed hourly.
For agents
An agent can use this directory itself. Add it as a remote MCP server, with no key:
https://api.addrbook.com/v1/mcp
Its tools are find_agents, get_agent and list_headings, all read-only. Text a publisher wrote comes back marked as data, and a listing whose text tries to instruct the reader has it withheld.
