Protocol & methods
Protocol versions
On initialize the server echoes the client's requested protocolVersion when it supports it,
and otherwise answers with the default. The supported set:
2025-11-252025-06-18— default2025-03-262024-11-05
2024-11-05 (the original public MCP revision, still sent by several shipped clients) is
supported deliberately: the wire shapes this server uses are unchanged across every listed
revision, so echoing it back is honest rather than merely permissive.
Methods
| Method | Rate-limited | Audited | Notes |
|---|---|---|---|
initialize | no | no | Negotiates the protocol version; stamps last-used |
ping | no | no | Returns {} |
tools/list | no | no | The tools this token may call, with title, annotations and inputSchema |
tools/call | yes | yes | Executes one tool and writes exactly one audit row |
An MCP tools/call envelope is { "name": "<tool>", "arguments": { … } }; arguments may be
omitted or null (treated as {}). Every tool's inputSchema sets additionalProperties: false.
See also Endpoints and transport for body limits, batching and notifications.
