Every REST operation and the MCP tool generated from it, derived from the spec the operation is implemented against.
The REST API is the source of truth and the MCP surface is generated from it. So is this: 37 operations, 35 of them on the MCP surface, one page each, naming the call and the tool together.

Signing in (/api/auth), API keys (/api/account) and the OAuth endpoints at the root have no spec, and that is the decision rather than an omission: a path outside/api/v1 gets no MCP tool, so keeping them specless is what keeps a credential-minting call off the surface an agent can reach.
Reconnecting after a release
An MCP client reads the tool list once, at connect. An operation renamed or added after that is invisible to it until it reconnects. Flow releases often, so a session left open across one is running against a tool list that may already be behind the35 tools this build serves. The server names its own build in the same handshake a client already makes: this deployment answers as v0.119.0. There is no push notice yet when the number moves. Reconnect after a release you know happened, or when a call that should exist answers "not found."
