SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables developers to quickly create MCP servers that expose tools for LLMs, removing the need to hand‑craft protocol handling and boilerplate code.

Core Features & Use Cases

  • Multi‑language templates: Ready‑to‑run Python (FastMCP) and TypeScript (MCP SDK) server skeletons.
  • Tool definition framework: Simple decorators or SDK calls to declare tool name, description, typed parameters, and return types.
  • Authentication & resource support: Built‑in patterns for loading API keys from environment variables and exposing read‑only resources. Use it to build services such as a weather lookup API, document search engine, or any custom backend that LLMs can call safely.

Quick Start

Use the mcp-builder skill to create a Python MCP server with a weather lookup tool and a document search tool.

Frequently Asked Questions about mcp-builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build an MCP server to extend LLM tool capabilities?▼

To build an MCP server, use templated Python or TypeScript skeletons to define tool interfaces, type safety, and authentication handling for reliable LLM integration. This removes the need to hand-craft protocol handling and boilerplate code.

Can I define MCP tools using both Python and TypeScript?▼

Yes, you can define MCP tools using Python with FastMCP or TypeScript with the MCP SDK. Both provide ready-to-run server skeletons and simple decorators or SDK calls to declare tool names, typed parameters, and return types.

How do I handle authentication when exposing custom APIs to LLMs?▼

Handle authentication for LLM tool integration by using built-in patterns to load API keys from environment variables. This allows your MCP server to securely connect to external services without hardcoding sensitive credentials.

What is the best way to expose a document search engine to an LLM?▼

The best way to expose a document search engine to an LLM is by building an MCP server. It provides a tool definition framework to declare typed parameters and return types, enabling LLMs to safely call your custom backend.

Do I need to manually write protocol handling for MCP servers?▼

No, you do not need to manually write protocol handling for MCP servers. The mcp-builder provides templated server code that removes the need to hand-craft boilerplate, handling the protocol automatically for reliable LLM tool integration.
