MCP Server Builder
Point it at any API docs URL. Three chained AI agents read the docs, select the best endpoints, and write a fully installable Python MCP server — automatically.
Any API, turned into a Claude tool.
- Reads raw API documentation — no manual endpoint mapping required
- Selects the most useful endpoints and writes typed Python tool functions
- Output installs directly into Claude Code with a single command
Three agents, one output.
-
Doc Reader
Scrapes the API documentation URL with Firecrawl, extracts available endpoints, and passes a structured summary to the next agent.
-
Tool Planner
Reviews the endpoint list and selects the subset most useful for an AI assistant — filtering out low-value or redundant operations.
-
Code Writer
Generates a complete FastMCP Python server with typed functions, docstrings, and error handling — ready to install with
pip install fastmcp.

I run it live against the Hacker News API — no cuts, no prep. Three agents fire in sequence, and a working MCP server comes out the other side in under a minute.
