DefaultJsonSchemaValidator ​

Defined in: packages/core-internal/src/validators/cfWorkerProvider.ts:50

@cfworker/json-schema-backed JSON Schema validator. See @modelcontextprotocol/{client,server}/validators/cf-worker for the customisation entry point.

Default validates as JSON Schema 2020-12 (SEP-1613). Schemas declaring a different $schema are rejected with a plain Error. Passing an explicit draft to the constructor overrides this — that draft is used for every schema regardless of $schema.

Examples ​

Use with default configuration (2020-12, shortcircuit on)

ts
const validator = new CfWorkerJsonSchemaValidator();

Use with custom configuration

ts
const validator = new CfWorkerJsonSchemaValidator({
    draft: '2020-12',
    shortcircuit: false // Report all errors
});
