Discover Awesome MCP Servers

Build

Okay, I can help you understand how to use the TypeScript SDK to create different MCP (Model Configuration Protocol) servers. However, I need a little more information to give you the *most* helpful and specific answer. Please tell me: 1. **What MCP server are you trying to create?** Are you trying to create a custom MCP server for a specific game, or are you trying to create a generic MCP server? 2. **What TypeScript SDK are you referring to?** There are many TypeScript SDKs that could be used to create an MCP server. Please provide the name of the SDK or a link to the documentation. 3. **What functionality do you need?** What specific features do you need your MCP server to support? For example, do you need to support authentication, authorization, or data validation? In the meantime, here's a general outline of how you might approach creating an MCP server using TypeScript, assuming you're building a custom server and not using a pre-built SDK (which would have its own specific instructions): **General Approach (Custom Implementation):** 1. **Project Setup:** * Initialize a new TypeScript project: ```bash mkdir my-mcp-server cd my-mcp-server npm init -y npm install typescript --save-dev npm install express body-parser cors --save # Common dependencies for a web server npm install --save-dev @types/node @types/express @types/body-parser @types/cors # Type definitions npx tsc --init # Initialize tsconfig.json ``` * Configure `tsconfig.json`: Adjust settings like `target`, `module`, `outDir`, `rootDir`, `esModuleInterop`, and `strict` to suit your project's needs. A basic example: ```json { "compilerOptions": { "target": "es6", "module": "commonjs", "outDir": "./dist", "rootDir": "./src", "strict": true, "esModuleInterop": true, "skipLibCheck": true, "forceConsistentCasingInFileNames": true }, "include": ["src/**/*"], "exclude": ["node_modules"] } ``` 2. **Define Data Structures (Interfaces/Types):** * Create TypeScript interfaces or types to represent the data structures used in the MCP protocol. This will depend entirely on the specific MCP protocol you're implementing. For example: ```typescript // src/types/mcp.ts export interface ModelConfiguration { modelId: string; version: number; parameters: { [key: string]: any }; } export interface MCPRequest { requestId: string; action: "get" | "set" | "delete"; modelId?: string; configuration?: ModelConfiguration; } export interface MCPResponse { requestId: string; status: "success" | "error"; data?: ModelConfiguration | null; error?: string; } ``` 3. **Implement the Server (using Express.js):** * Create an Express.js server to handle MCP requests. ```typescript // src/index.ts import express, { Request, Response } from 'express'; import bodyParser from 'body-parser'; import cors from 'cors'; import { MCPRequest, MCPResponse, ModelConfiguration } from './types/mcp'; const app = express(); const port = 3000; app.use(cors()); app.use(bodyParser.json()); // In-memory storage (replace with a database in a real application) const modelConfigurations: { [modelId: string]: ModelConfiguration } = {}; app.post('/mcp', (req: Request, res: Response) => { const mcpRequest: MCPRequest = req.body; console.log("Received MCP Request:", mcpRequest); switch (mcpRequest.action) { case "get": if (!mcpRequest.modelId) { sendErrorResponse(res, mcpRequest.requestId, "Model ID is required for 'get' action."); return; } const config = modelConfigurations[mcpRequest.modelId]; if (config) { sendSuccessResponse(res, mcpRequest.requestId, config); } else { sendSuccessResponse(res, mcpRequest.requestId, null); // Model not found } break; case "set": if (!mcpRequest.configuration) { sendErrorResponse(res, mcpRequest.requestId, "Configuration is required for 'set' action."); return; } if (!mcpRequest.configuration.modelId) { sendErrorResponse(res, mcpRequest.requestId, "Model ID is required in the configuration for 'set' action."); return; } modelConfigurations[mcpRequest.configuration.modelId] = mcpRequest.configuration; sendSuccessResponse(res, mcpRequest.requestId, mcpRequest.configuration); break; case "delete": if (!mcpRequest.modelId) { sendErrorResponse(res, mcpRequest.requestId, "Model ID is required for 'delete' action."); return; } delete modelConfigurations[mcpRequest.modelId]; sendSuccessResponse(res, mcpRequest.requestId, null); break; default: sendErrorResponse(res, mcpRequest.requestId, "Invalid action."); } }); function sendSuccessResponse(res: Response, requestId: string, data: ModelConfiguration | null) { const response: MCPResponse = { requestId: requestId, status: "success", data: data, }; res.json(response); } function sendErrorResponse(res: Response, requestId: string, errorMessage: string) { const response: MCPResponse = { requestId: requestId, status: "error", error: errorMessage, }; res.status(400).json(response); } app.listen(port, () => { console.log(`MCP Server listening at http://localhost:${port}`); }); ``` 4. **Implement MCP Logic:** * Implement the core logic for handling MCP requests. This will involve: * Parsing the request. * Validating the request. * Retrieving, updating, or deleting model configurations. * Constructing the response. 5. **Data Storage:** * Choose a data storage mechanism to store model configurations. This could be: * In-memory storage (for simple prototypes). * A file-based database (e.g., SQLite). * A relational database (e.g., PostgreSQL, MySQL). * A NoSQL database (e.g., MongoDB, Redis). 6. **Error Handling:** * Implement robust error handling to gracefully handle invalid requests, data validation errors, and other potential issues. 7. **Authentication and Authorization (if needed):** * If your MCP server needs to be secure, implement authentication and authorization mechanisms to control access to model configurations. 8. **Build and Run:** * Compile the TypeScript code: `npm run build` (or `tsc` if you haven't configured a build script). * Run the server: `node dist/index.js` **Example Request (using `curl`):** ```bash curl -X POST -H "Content-Type: application/json" -d '{ "requestId": "123", "action": "set", "configuration": { "modelId": "myModel", "version": 1, "parameters": { "param1": "value1", "param2": 123 } } }' http://localhost:3000/mcp ``` **Important Considerations:** * **Security:** If your MCP server will be exposed to a network, security is paramount. Use HTTPS, implement authentication and authorization, and carefully validate all input. * **Scalability:** If you anticipate a high volume of requests, consider using a scalable architecture, such as a load balancer and multiple server instances. * **Monitoring:** Implement monitoring to track the health and performance of your MCP server. * **Testing:** Write unit tests and integration tests to ensure that your MCP server is working correctly. **Example `package.json` (with build script):** ```json { "name": "my-mcp-server", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "build": "tsc", "start": "node dist/index.js", "dev": "ts-node-dev --respawn src/index.ts" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "body-parser": "^1.20.2", "cors": "^2.8.5", "express": "^4.18.2" }, "devDependencies": { "@types/body-parser": "^1.19.5", "@types/cors": "^2.8.17", "@types/express": "^4.17.21", "@types/node": "^20.10.5", "ts-node-dev": "^2.0.0", "typescript": "^5.3.3" } } ``` **To run this example:** 1. Save the code into the appropriate files (e.g., `src/index.ts`, `src/types/mcp.ts`). 2. Run `npm install` to install dependencies. 3. Run `npm run build` to compile the TypeScript code. 4. Run `npm start` to start the server. **Next Steps:** Provide more details about the specific MCP server you're trying to create, the SDK you're using, and the functionality you need, and I can give you more tailored guidance.
