 * MCP tools.
 *
 * Unlike logging/feedback, this endpoint authenticates with the client's PRIVATE key (passed as the
 * `apiKey` config field and sent as `X-API-Key`), and it surfaces failures by THROWING rather than
 * returning `null`, so callers can show the error to the user. `dryRun: true` still applies here —
 * it skips the request and returns `null`, since some MCP tools (e.g. `close_optimization`) mutate
 * server state.
