FAQ

Questions Output Format Contract Checker owners ask.

  • 01

    What does this MCP do?

    It validates that JSON data produced by an AI agent matches a specific schema, checking for missing fields, type mismatches, and enum violations using validate_contract.

  • 02

    Can it fix schema errors automatically?

    It identifies if errors are fixable via check_coercion_possibility, which checks for simple type conversions like string to integer.

  • 03

    How do I see a summary of all errors?

    You can use the get_violation_summary capability to get a categorized report of all detected contract breaches.
