Graphql Schema Validator

Seo REST API MCP

Validate a GraphQL SDL schema and return errors, naming-convention warnings, and counts of types, queries, mutations, and subscriptions. Errors cover unbalanced braces, fields without a type, double colons, and malformed return types; warnings cover type names that are not PascalCase, field names that are not camelCase, and a missing Query type.
