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.
