| check_tool | Check one MCP tool name, description, and input schema against Toolcard cited rules. Returns findings. A finding with an answer page includes resource, a toolcard://answers URI to pass to resources/read. Does not store the tool. | Read-only |
| outcome_summary | Return the anonymous tally of called versus ignored reports on this server. Not a representative sample. | Read-only |
