Configuration

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

Integration with Claude Desktop

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

Windows

code $env:AppData\Claude\claude_desktop_config.json

macOS/Linux

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

Add the MCP Server to the Configuration

{
    "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.

Usage

1. Add an OpenAPI file.

2. Provide a prompt to validate it.

3. The validation results will be returned.
