This repository provides a Model Context Protocol (MCP) Server for validating OpenAPI specifications using APIMatic. The server processes OpenAPI files and returns validation summaries by leveraging APIMatic’s API.

• Validates OpenAPI 2.0 and 3.0 files
• Uses APIMatic’s API for comprehensive validation
• Supports both JSON and YAML formats
• Implements Model Context Protocol (MCP) for seamless integration

Ensure that Node.js v18+ is installed.

git clone https://github.com/apimatic/apimatic-validator-mcp.git
cd apimatic-validator-mcp

npm install

npm run build

To use the server, an APIMatic API key is required. Sign up at APIMatic and obtain the API key.

Modify the claude_desktop_config.json file to integrate the MCP server. If the file does not exist, create one in the following location:

code $env:AppData\Claude\claude_desktop_config.json

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

{
    "mcpServers": {
        "APIMatic": {
            "command": "node",
            "args": [
                "C:\\PATH\\TO\\PARENT\\FOLDER\\build\\index.js"
            ],
            "env": {
                "APIMATIC_API_KEY": "<Add your APIMatic token here>"
            }
        }
    }
}

Once configured, a hammer icon should appear in Claude Desktop. Open it to verify that the validate-openapi-using-apimatic tool is successfully integrated.

1. Add an OpenAPI file.
2. Provide a prompt to validate it.
3. The validation results will be returned.
