Feature & Specification Comparison
Tools & Capabilities Breakdown
MCP Graphql Tools (2)
introspect-schema
This tool retrieves the GraphQL schema. Use this first if you don't have access to the schema as a resource.
query-graphql
Execute GraphQL queries against the endpoint. By default, mutations are disabled unless `ALLOW_MUTATIONS` is set to `true`.
Sdcvalidator Tools (3)
validate_instance
Validate an XML instance against its SDC4 XSD schema. Returns pass/fail with error count and classified errors.
validate_and_report
Validate an instance and return a detailed report with two-tier (structural vs semantic) error classification.
check_schema_compliance
Check whether an XSD schema follows SDC4 principles (restriction only, no `xsd:extension`). Does not validate instances.
