What it is

A public registry that mirrors the official MCP registry, probes every remote endpoint without credentials, indexes tools for hybrid search, and scores each listing transparently. Agents reach it over REST or over MCP itself. Humans get the same data on the portal.

It is a registry, not a gateway: it never proxies traffic and never holds credentials. Connection blocks carry ${NAME} placeholders that your agent fills from its own secret store.

The flow

1. search — “send an email”, “query postgres”, “get weather for a city”.
2. get_server or list_tools — the descriptor with connection class, health, tools and trust.
3. get_connection — a minimal connection block for the preferred remote or package, formatted for your client.
4. Connect with your own MCP client. No human step for R0 servers, or for R1 when you already hold the named secret.

Every response carries next_actions with ready-to-use arguments, so an agent can chain the calls without reading these docs.

These docs for agents

Every page here exists as Markdown at the same path with .md, and /llms.txt lists them all.
