FAQPage Schema
How do I build an MCP server for LLMs to interact with external APIs?

Building an MCP server involves structured phases: research, planning, implementation, review, and testing. This workflow ensures well-designed tools and proper documentation for LLMs to interact with external services effectively.

What is the Model Context Protocol used for in LLM integration?

The Model Context Protocol (MCP) enables LLMs to interact with external services through well-designed tools. It provides a standardized protocol for building servers that expose external APIs to language models.

Can I use Python or TypeScript SDKs to develop an MCP server?

Yes, MCP server development supports both Python and TypeScript SDKs. The guide provides language-specific implementation references and documentation for both environments to facilitate external service integration.

What's the best way to test and evaluate an MCP server?

The best way to evaluate an MCP server is by creating comprehensive evaluations using the provided evaluation guide. This ensures you test the effectiveness of the server's tools and their interactions with external services.

Do I need to write documentation when creating an MCP server?

Yes, documentation is essential when creating an MCP server. The workflow includes a review phase and provides a documentation library with core MCP and SDK references to guide you in documenting your tools properly.
