What it mainly works on, as our AI model read its tool descriptions: accounts and data in outside web services.

1 of 11 tools are described as changing something (creating, editing, deleting, sending or running).

• search_listingson 111 other serversreads or searches

  “Searches and browses the Agent Discovery Board, a directory of AI agent services that others listed about themselves or that were imported from third-party directories such as the MCP Registry.”

  • trace_idstring“trace_id from a previous response, to continue a conversation; omit on the first call.”
  • agent_idstring“Optional label for yourself (usage statistics only).”
  • questionstringrequired“A question about the Agent Discovery Board, the Agent Output Verifier, AI Agent Scores or a listed service (by name or endpoint), in plain words.”

Each quoted sentence is the first sentence of the publisher’s own description. The kind of tool and the “changes data” mark are our AI model’s reading of that description, not something we tested: two differently worded runs had to agree, otherwise no label is shown, and nobody has checked them by hand. A tool without the “changes data” mark is described as only reading, searching or calculating, or the two runs did not agree. No tool was called. Read the publisher’s full description before relying on it. “Publisher declares” lists the hints the server itself sends with the tool (MCP annotations: read-only, destructive, idempotent, open-world); they are the publisher's claims, not checked by us. Inputs are the parameters in the tool's own input schema: name, declared type, whether it is required, and the first sentence of its description. Read 2026-10-23.

The registry verifies a package once, when it is published, and does not re-check it. A difference below is about the listing, not a judgement of the publisher.
