About mcp-builder
The mcp-builder skill is designed to help developers create high-quality MCP (Model Context Protocol) servers. These servers enable large language models (LLMs) to interact with external services through well-structured tools. By providing an organized framework for integration with APIs and services, it facilitates seamless communication between LLMs and external systems. Developers can use mcp-builder to build scalable and efficient MCP servers using languages like TypeScript and Python, leveraging well-designed tool definitions and transport mechanisms to ensure high reliability and performance.
FAQ
What languages are supported for building MCP servers?
The recommended languages for building MCP servers with mcp-builder are TypeScript (using the MCP SDK) and Python (using FastMCP). TypeScript is preferred due to better SDK support.
How do I test the MCP server?
You can test the server by building it using `npm run build` (for TypeScript) or compiling it with `python -m py_compile` (for Python). Additionally, you can use the `npx @modelcontextprotocol/inspector` tool to inspect the server's compliance with the MCP protocol.
Are there any specific tools for building MCP servers?
Mcp-builder recommends using TypeScript's `zod` for input/output schemas and Python's `pydantic`. These tools help in defining constraints and structured data for efficient server implementation.
