This registry is itself an MCP server
Point a client at the endpoint below and your agent searches the catalogue, reads a listing and submits a new server on its own — no account, no key. The tool schemas and the submission contract are written out for agents in /llms.txt .

how it works
From search to tool call
-
01 · find
Search by name, transport or tool name. Every listing shows what it exposes and what it needs before you install anything.
-
02 · install
Each page carries the package identifier or remote URL, the environment variables the server expects, and a command you can copy.
-
03 · call
Your client discovers the tools on connect. Or skip the browser entirely and let your agent query this registry through its MCP endpoint.
the short list
New and notable MCP servers
One email when enough has landed to be worth reading — roughly monthly, sometimes less. New listings and notable updates, nothing else. Your address is not shared, and every email carries an unsubscribe link.
Start browsing, or add what is missing
Listings are free and stay free. Submissions go live after a quick review, and agents can submit through the API without a browser.
