概览
What is MCP Lab?
MCP Lab is a personal experimentation repository for learning and testing the Model Context Protocol (MCP) using the TypeScript SDK. It contains multiple sub-projects: a basic MCP server (mcp-server-dummies), a Text-to-SQL server for SQLite (mcp-lab-text2sql), and a client that integrates MCP with OpenAI’s Responses API.
How to use MCP Lab?
Each sub‑project is installed and run separately. Navigate to a project (e.g. mcp-server-dummies) and run npm i, then npm run build (compiles with tsc) and npm run dev (runs with ts-node). Debug with npm run test which launches the MCP Inspector at http://localhost:6274. Servers can be added to Claude Desktop via claude_desktop_config.json under AppData/Roaming/Claude on Windows.
Key features of MCP Lab
- Basic MCP server for learning and quick testing.
- Text‑to‑SQL server letting you chat with SQLite databases in natural language.
- MCP client that bridges MCP tools with OpenAI’s Responses API.
- Supports debugging via the MCP Inspector visual interface.
- All projects require Node.js >= v20.
- Licensed under MIT.
Use cases of MCP Lab
- Experimenting with the MCP SDK and understanding protocol mechanics.
- Building and testing a Text‑to‑SQL assistant over a local SQLite database.
- Connecting MCP servers to an OpenAI‑powered agent (via the provided client).
- Prototyping and debugging MCP tools before production deployment.
常见问题
How can I debug an MCP server in this lab?
Run `npm run test` inside a server project – this launches the MCP Inspector at `http://localhost:6274` for interactive testing.
Can I use these MCP servers with Claude Desktop?
Yes. Edit `claude_desktop_config.json` (located in `AppData/Roaming/Claude` on Windows) and add entries with the `node` command pointing to the compiled `dist/index.js` of each server. Remember to run `npm run build` first.
Are these MCP servers directly compatible with OpenAI?
No. MCP tool schemas differ from OpenAI’s function‑calling format. MCP Lab includes a client project (`mcp-client`) that transforms tools for use with the OpenAI Responses API. When defining tool arguments with Zod, OpenAI requires all params be required, forbids `min`/`max` on integers, and disallows `default` values.
What data does the Text‑to‑SQL server work with?
The `mcp-lab-text2sql` server interacts with a SQLite database, but the README does not specify which database or its location; the server is designed to chat with your own SQLite data.
