Welcome to LeanMCP

LeanMCP is the fastest way to build and deploy MCP Servers.

​
What are MCPs?

Think of MCPs as UI for AI agents. Every tool call is like a click. Your tools work great with buttons and forms for humans. They also work with APIs for developers. But AI agents need something different - they need Model Context Protocol (MCP). MCPs help AI understand your tools. They show AI agents:
  • What each tool does
  • How to use each tool
  • When to use each tool

​
Why MCPs Matter

AI agents are confused without MCPs. Imagine a webpage with 1000 buttons scattered everywhere. That’s how AI feels when it sees 50-100 API tools without proper MCPs. Good MCPs make AI agents work better.

​
Building Good MCPs is an Art

You want to:
  • Reduce wrong tool calls - Less confusion for AI
  • Make tools easy to find - Better performance
  • Keep users happy - They’ll use your tools more

​
Perfect for Testing AI Workflows

MCPs are great for trying new ideas:
  1. Old way: Code everything → Test → Hope it works
  2. New way: Build MCP → Test with AI → See if it works
Most AI providers (like Anthropic and OpenAI) support MCPs. Going from test to production is easy.
