Every MCP surface, plus the static half of the acceptance gate.

  • Capability-aware resources & prompts lanes (both protocol eras): RES-01..04, PROMPT-01..03, CAP-02/03. Surfaces a server does not advertise are skipped, never failed; surfaces it advertises must work. CACHE-01 now validates ttlMs/cacheScope on every cacheable result observed.
  • Contract engine: mcp-proof inspect freezes the served surface into a fingerprinted manifest (identical surface ⇒ identical contract_sha256); mcp-proof diff classifies every change as BREAKING / ADDITIVE / METADATA and exits non-zero on breaking ones — optional→required flips, type/enum/constraint tightening, removed output fields and weakened readOnlyHint/destructiveHint annotations all count.
  • Annotations-first call planning: MCP tool annotations outrank the name heuristic in both directions; mcp-proof plan shows the AUTO-CALL / SKIPPED decision and its basis per tool before anything touches production.
  • Recorder, replayer and plan now paginate tools/list fully.

With all three surfaces and both eras covered, the README's "any MCP server" claim is back — earned this time.
