4 tools
Changes things 3Claude Code: ask
error_routeDiagnose a failed API, HTTP, MCP, or tool request and return a bounded safe next action.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Diagnose a failed API, HTTP, MCP, or tool request and return a bounded safe next action. Use it after a request fails when the safe next step is unclear. Provide a status, response, or error text; it does not execute requests or verify undocumented fixes. Price: $0.002 USD per call via x402.
request_repairRepair a failed API or HTTP request using only supplied schema and error evidence.No findings
Why it is in this group
- The name "request_repair" says "request": a word for a change.
Description, as the server wrote it Repair a failed API or HTTP request using only supplied schema and error evidence. Use after error_route identifies a request-shape or input problem. Returns the smallest justified request changes and abstains when evidence is insufficient. Price: $0.005 USD per call via x402.
stop_searchDecide whether another search or paid retrieval is worth the cost based on the scope already checked.No findings
Why it is in this group
- The name "stop_search" says "stop": a word for a change.
Description, as the server wrote it Decide whether another search or paid retrieval is worth the cost based on the scope already checked. Use after several search or source checks when you need to decide whether to continue or return a scoped not-found result. It does not prove universal absence and performs no searches itself. Price: $0.003 USD per call via x402.
Only reads 1Claude Code: allow
source_routeFind likely authoritative or machine-readable sources when you know what information you need but not where to retrieve it.No findings
Why it is in this group
- The description's first verb is "find": a word for reading.
Description, as the server wrote it Find likely authoritative or machine-readable sources when you know what information you need but not where to retrieve it. Provide a goal and optional publisher domain or start URL; it returns ranked candidate routes and bounded evidence. Use it before blind searching. Do not use it when you already have the correct source or only need reasoning over supplied context. Price: $0.02 USD per call via x402.
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
