Module validation

JSON Schema validation

This module provides configurable JSON Schema validation for the MCP SDK. Choose a validator based on your runtime environment:

AjvJsonSchemaValidator: Best for Node.js (default, fastest) Import from: @modelcontextprotocol/sdk/validation/ajv Requires peer dependencies: ajv, ajv-formats
CfWorkerJsonSchemaValidator: Best for edge runtimes Import from: @modelcontextprotocol/sdk/validation/cfworker Requires peer dependency: @cfworker/json-schema

Example

// For Node.js with AJV
import { AjvJsonSchemaValidator } from '@modelcontextprotocol/sdk/validation/ajv';
const validator = new AjvJsonSchemaValidator();

// For Cloudflare Workers
import { CfWorkerJsonSchemaValidator } from '@modelcontextprotocol/sdk/validation/cfworker';
const validator = new CfWorkerJsonSchemaValidator();
