Pydanticcontract Mcp

clauxel/pydantic-contract-mcp

A paid remote server that wraps Pydantic AI validation into four MCP tools: contract_validate, schema_diff, repair_hint, and contract_receipt. You get structured verdicts on whether JSON matches your Pydantic schemas, diffs between schema versions, hints for fixing validation failures, and audit-ready usage logs. Runs over streamable HTTP with bearer token auth. Reach for this when you need repeatable validation checks in agent workflows or CI pipelines and want the evidence trail that comes with it. The repository is just docs; the actual service runs hosted at pydanticcontract.clauxel.com with paid plans.
