About ajv-validator-mcp-server

ajv-validator-mcp-server is a minimal MCP server for validating JSON data against JSON Schema with AJV. It is intended for MCP-compatible clients that need validation results or error details.

Key features

  1. 01Validate JSON data against JSON Schema
  2. 02Use ajv-formats for format checks
  3. 03Return validation results or errors
  4. 04Build and run as a TypeScript project

Use cases

  1. 01Check JSON payloads against a schema
  2. 02Identify schema validation errors
  3. 03Test validation interactively with MCP SDK Inspector

MCP support

It exposes the `ajv-validator` tool to MCP clients, accepting a schema and data and returning a result message or validation errors.

Details

From the project README

ajv-validator-mcp-server

This project provides a minimal Model Context Protocol (MCP) server for validating JSON data against JSON Schema using AJV.

Features

  • Exposes an MCP tool ajv-validator for validating JSON data against a provided schema.
  • Integrates ajv-formats for extended format validation.
  • Designed for easy integration with MCP-compatible clients and tools.

Usage

  1. Build the project: Install dependencies and compile TypeScript sources.

  2. Configure MCP server: Copy and edit the example configuration file to specify the Node.js binary and the built server entrypoint.

  3. Start the server: Use npm start or run the built file directly with Node.js.

Tool API

ajv-validator
  • Description: Validates JSON data against a provided JSON Schema using AJV.
  • Parameters:
    • schema (object): The JSON Schema definition.
    • data (object): The JSON data to validate.
  • Returns: Validation result message or a list of errors.

Development

  • Written in TypeScript (src/), output in dist/.
  • Main MCP server entrypoint: src/index.ts.
  • Includes scripts for building, starting, and watching the project.

MCP SDK Inspector

The project is compatible with the MCP SDK Inspector, a tool for exploring and testing MCP servers and tools. Use the Inspector to:

  • Discover and invoke the ajv-validator tool interactively.
  • Inspect tool parameters, responses, and error messages.
  • Debug and validate your MCP server integration.

Running the MCP SDK Inspector

To start the MCP SDK Inspector for this project, run:

npm run inspector

This command launches the Inspector and connects it to your built MCP server, allowing you to interactively test and debug the ajv-validator tool.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
