| 1 | //! The MCP server's tools: a few resource tools, each with an `action`. |
| 2 | //! |
| 3 | //! Every operation is one action of one tool. A call is dispatched to the |
| 4 | //! operation it names, so permissions, the audit log, billing and outcomes |
| 5 | //! are exactly those of the REST API. A token sees only the actions its |
| 6 | //! scopes allow, and a tool none of whose actions it may use is not listed. |
| 7 | //! |
| 8 | //! The listed input schema is one flat object: `action`, then every field |
| 9 | //! any of its actions takes. Which fields each action needs is in the |
| 10 | //! `action` field's description and checked on every call. Claude's API, |
| 11 | //! and so most MCP clients, refuse a tool whose input schema has `oneOf` |
| 12 | //! at its top level, so the schema keyed by action, with each action's |
| 13 | //! required fields, is [`discriminated`], published on the server's card |
| 14 | //! and in the docs. |
