API, MCP & AI assurance

512 KiB per JSON input, 32 nesting levels, 20,000 JSON nodes, 512 nodes per schema, 500 API operations or MCP tools and 1,000 findings. Checks time out after five seconds. No remote reference fetching, API calls or AI inference.

OpenAPI 3.0/3.1 static changes and a documented JSON Schema 2020-12 subset. MCP checks compare complete tools/list catalogs by unique name; annotations are hints, not permission enforcement. AI regression checks use your expected cases and observed runs: exact JSON-pointer values, schemas, exact source quotes and optional latency/cost budgets. They do not judge semantic truth or prevent hallucinations. Missing observations fail, rather than counting as zero.

Formats, content decoding, dynamic/recursive references and unknown schema keywords are rejected. Inputs stay in session memory; no uploads or automatic save. Reports omit raw documents, but paths and findings can contain confidential references. Review before sharing. Load an illustrative example to inspect each input contract.
