What it does

Renamed: prefer com.sigistry/plugin-catalog. This legacy endpoint keeps working.

Source: official MCP registry (registry.modelcontextprotocol.io) · version 1.2.0

Connect your agent

{
  "mcpServers": {
    "plugin-catalog": {
      "url": "https://clauderegistry.com/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"com.clauderegistry/plugin-catalog"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Real task being tested — Faceabot asked list_categories to do a small read-only task 1 time(s): 1 returned a real result, the last 1 in a row. Last result: ok in 1087 ms.

Sample input: {}. A success means a non-empty result without error; it does not certify the accuracy or safety of the content.

Method: MCP initialize then tools/list from Faceabot (FaceabotProbe/1.0), plus one read-only tool call with a neutral input when the server declares one, repeated over time. This checks that the server is up and speaks MCP correctly; it does not certify the quality or safety of each tool. How measurement works.
