Supported formats & limitations
  • Supply tools/list result objects containing tools arrays, not JSON-RPC envelopes. Every tool needs a unique non-empty name and object inputSchema; outputSchema is optional.
  • Maximum 100 tools per catalogue; schemas use the schema checker policy (draft-07/2020-12, local references, RE2, depth 48).
  • Heuristic flags new required properties, narrowed enums, removed tools/properties, changed types and constraints. These are candidates for review, not proofs of compatibility.
  • Changes to refs/combinators and other complex constraints are explicitly unassessed. Descriptions/annotations are metadata changes, not semantic compatibility evidence.
  • SHA-256 schema signatures ignore object key order but retain array order and numeric spelling. At most 200 findings, with truncation declared.

Execution budget: 5s; output limit: 4096 KiB. Browser worker startup has a separate 3s allowance.
