OpenAPI Client Generator MCP server

This MCP server generates TypeScript API clients from OpenAPI/Swagger specifications. It creates axios-based clients that make it easy to interact with APIs defined by OpenAPI specs.

Installation

To use the openapi-client-generator MCP server with Claude Desktop, you need to add the server configuration to your Claude Desktop config file.

Configuration Location

Depending on your operating system, the configuration file is located at:

• MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json

Adding Server Configuration

Add the following configuration to your claude_desktop_config.json file:

{
  "mcpServers": {
    "openapi-client-generator": {
      "command": "node",
      "args": [
        "< PATH TO >/openapi-client-generator/build/index.js"
      ]
    }
  }
}

Make sure to replace < PATH TO > with the actual path to the openapi-client-generator directory on your system.

Usage

The openapi-client-generator MCP server provides the following functionality:

Available Resources

• Generates an axios-based API client from OpenAPI/Swagger specifications
• The generated client can be used to interact with the API described in the specs

Using the Generate Client Prompt

You can generate an API client using the generate_client prompt. This prompt takes an OpenAPI specification and generates a TypeScript client for interacting with the API.

Example usage with Claude:

1. Tell Claude you want to generate an API client from an OpenAPI specification
2. Provide the OpenAPI specification in JSON or YAML format
3. Ask Claude to use the generate_client prompt to create the client

Debugging

If you encounter issues, you can use the MCP Inspector for debugging:

npm run inspector

This will provide a URL to access debugging tools in your browser, which can help identify any communication problems between Claude and the MCP server.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
