SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill guides you through creating high-quality MCP (Model Context Protocol) servers, enabling Large Language Models (LLMs) to interact with external services through well-defined tools.

Core Features & Use Cases

  • MCP Server Development: Provides a structured workflow for building MCP servers in TypeScript or Python.
  • Tool Integration: Focuses on designing effective tools for LLMs, including schema definition, naming conventions, and error handling.
  • Evaluation Framework: Guides the creation of comprehensive evaluations to test the effectiveness of the MCP server.
  • Use Case: You need to expose a set of internal APIs to an LLM so it can manage project tasks. This Skill will help you build the MCP server that defines these APIs as tools for the LLM.

Quick Start

Follow the steps in the Skill to build a new MCP server for your external services.

Frequently Asked Questions about mcp-builder

FAQPage Schema
How do I build an MCP server to expose APIs to an LLM?▼

Yes, you can develop MCP servers using both TypeScript and Python. The workflow covers planning, implementation, review, testing, and evaluation to ensure robust API integration and tool design within either framework.

What is the best way to design tools for an LLM in an MCP server?▼

The best way to design LLM tools in an MCP server is to focus on schema definition, naming conventions, and robust error handling. Well-defined tools allow the model to understand and trigger external API actions accurately.

How do I test and evaluate an MCP server?▼

You test an MCP server by creating a comprehensive evaluation framework. This involves testing the effectiveness of the defined tools, checking API integration stability, and verifying how accurately the LLM interacts with external services.

Do I need to define schemas for tools when integrating external services via MCP?▼

Yes, schema definition is required when integrating external services via MCP. Defining schemas ensures the LLM understands the exact input parameters and expected outputs for each tool, preventing execution errors.
