editorial:auto 12d

The v1.33.14 release reintroduces a lean, flat outputSchema for tools/list and individual tool entries, reducing payload size while preserving schema information.

Why it matters: Reduces API response payloads by presenting a flat outputSchema on tools/list and each tool entry, improving efficiency without losing schema details.

Full changelog

Lean (flat) outputSchema reintroduced on `tools/list`

v1.33.13 stripped outputSchema entirely to fix a Smithery catalog-gateway availability issue (309KB→81KB) — but that dropped Smithery's "Output schemas" quality criterion to 0/53 (−10.37pt).

This release reintroduces a lean, flat outputSchema per tool: the success model's top-level field names + primitive types only (no $defs/$ref/anyOf/prose, ~0.5KB/tool). Each tool re-advertises its output shape and the whole tools/list payload stays at ~104.5KB — well under the gateway buffer.

Changes

New _leanify_output_schema() transform in the MCP proxy (wire-only; never touches the FastMCP tool objects). Applied on both the fast-path cache and the lazy-rebuild path.
required is filtered to advertised properties (valid JSON Schema).
tools/call validation + structuredContent are runtime concerns — unaffected.

Verification

tools/list (prod): 53/53 tools carry a flat outputSchema, payload 104.5KB, no $ref on the wire.
Tests: 2467 passed (test_mcp.py flips ABSENT→PRESENT+FLAT invariants + per-tool/payload budgets).
MCP tools/Resources/Prompts counts unchanged (53/7/3).
