MCP Router: schema.defaultDialect

schema.defaultDialect selects the JSON Schema dialect used to compile tool input and output schemas.

  • Type: String
  • Default and only supported value: https://json-schema.org/draft/2020-12/schema

A tool schema may omit $schema and inherit this dialect. If $schema is present, it must equal the configured dialect exactly. Any other configured or per-tool dialect rejects the router configuration during startup or reload.
