Add the query-format MCP tool and RawTreeClient.formatQuery, using authenticated POST /v1/query-format without executing SQL. The tool preserves complete SQL and the full { "formatted": "..." } response, follows existing organization/cluster/database defaults and explicit-scope mode, validates success response shape, and forwards MCP cancellation to the HTTP request.

Example tool arguments:

{ "sql": "select 1; select 'hello'", "organization": "acme", "cluster": "production" }

The API accepts 50 MiB JSON requests, 100 MiB formatted output, and a 30-second formatting timeout. Native inline INSERT VALUES data is preserved verbatim without completeness/schema validation. Raise the bundled HTTP (previously 100 KiB) and stdio (previously 10 MiB) request limits to a bounded 51 MiB for the API payload plus MCP envelope. Client/hosting gateway limits can still be smaller; document that boundary.

Bump MCP 0.3.5 → 0.3.6 and add the changelog entry. The frozen pnpm lockfile needs no change because it does not record the root package version. No release is published.

Dependency: Platform #1468, inspected at 397dc652846ad5820073641c19301ea154289cce. Deployment is required; this PR does not establish production endpoint availability.

Validation:

• Frozen pnpm dependency installation, pnpm lint, pnpm test (197 passed), and pnpm build passed.
• Tests cover authenticated route/body, defaults and overrides, explicit-scope discovery, full large SQL/output, structured error statuses, malformed responses, and MCP cancellation.
• Four real transport tests round-trip 11 MiB documents over HTTP and stdio in both legacy and modern protocol modes, using the built stdio entrypoint.
• Executable HTTP cancellation proof confirms active API requests close for both protocol modes.
• Existing local Platform #1468 stack: real native 11 MiB formatting and syntax errors verified through legacy and modern stdio. No Platform files changed.
• Codex autoreview (--mode local --max-priority P3) and thermo-nuclear maintainability review complete; final review has no actionable findings. TruffleHog clean. The earlier empty-SQL finding was rejected against the Platform handler, which explicitly rejects empty/whitespace SQL; corrected review passed.

Companion: CLI #82.

Note

Low Risk
Read-only formatting with no SQL execution; main operational change is higher MCP request buffers, which can increase memory use for very large payloads.

Overview
Adds a query-format MCP tool and RawTreeClient.formatQuery, calling authenticated POST /v1/query-format to return the full { "formatted": "..." } payload without executing SQL or writing query logs. Scope follows existing organization/cluster/database defaults and explicit-scope mode; success responses are validated and MCP cancellation is forwarded to the outbound HTTP request via a new AbortSignal on the API client.

HTTP and stdio transports now accept MCP requests up to 51 MiB (MAX_MCP_REQUEST_BYTES) so large SQL can fit under the API’s 50 MiB JSON cap plus MCP envelope overhead. Package version is 0.3.6 with README/changelog updates; tests cover the tool, errors, cancellation, and ~11 MiB round-trips over real HTTP/stdio paths.

Requires Platform POST /v1/query-format (Platform PR #1468).
