Setting Up MCP in Cursor with Claude Desktop

steps

1. Create a project directory:

   bashCopy

   mkdir my-mcp-server
   cd my-mcp-server

2. Initialize the project:

   bashCopy

   npm init -y

3. Install required dependencies:

   bashCopy

   npm install typescript @openai/ai npm-run-all

steps

1. Create the project structure:

   bashCopy

   mkdir src
   touch src/index.ts

2. Configure package.json: Open package.json in your editor and update it with the following:

   jsonCopy

   {
     "name": "my-mcp-server",
     "version": "1.0.0",
     "type": "module",
     "scripts": {
       "build": "tsc"
     },
     "files": ["build"]
   }

3. Add a TypeScript configuration: Create a tsconfig.json file in the project’s root directory:

   jsonCopy

   {
     "compilerOptions": {
       "target": "ES2020",
       "module": "ES2020",
       "outDir": "build",
       "rootDir": "src",
       "strict": true,
       "esModuleInterop": true,
       "moduleResolution": "node"
     },
     "include": ["src"]
   }

steps

1. Set up index.ts in src: Write the following code to define your server:

   typescriptCopy

   import { createServer } from "@openai/ai";
   
   const server = createServer({
       name: "WeatherMCPServer",
       capabilities: {
           tools: {
               getWeather: {
                   description: "Fetch current weather for a location",
                   parameters: { location: { type: "string" } },
                   action: async (params) => {
                       // Dummy weather data
                       return { temperature: "72°F", location: params.location };
                   },
               },
           },
       },
   });
   
   server.listen().then(() => {
       console.log("MCP server is running.");
   });

2. Add helper functions: If your tools require API calls or other logic, you may write functions within this file.

3. Finalize the server: Ensure all code logic for your MCP tools, resources, and server metadata is implemented.

steps

1. Build the server:

   bashCopy

   npm run build

2. Copy the file path for deployment: Locate the generated build/index.js file and copy its absolute file path.

3. Configure Claude Desktop:

   • Open Claude Desktop and go to Settings.
   • Enable Developer Mode.
   • Edit the claude_desktop_config.json file in the configuration interface.
   • Replace the mcp_server_path field with the absolute path to your index.js.

4. Restart Claude Desktop: Close and reopen Claude Desktop to apply the changes.

5. Verify the integration:

   • Open a chat in Claude Desktop.
   • Test your added MCP tools by querying them interactively in the chat interface.
