Summary

Build and deploy MCP servers in Python using FastMCP with tools, resources, and prompts.

  • Scaffolds a working Python MCP server from a description; supports tools (callable functions), resources (readable data), and prompts (reusable templates)
  • Includes local testing modes (direct run, dev mode with auto-reload, HTTP transport) and MCP Inspector integration
  • Deploys to FastMCP Cloud, Docker, or Cloudflare Workers; pre-deploy checklist catches common issues like missing module-level server instances and hardcoded secrets
  • Provides 30+ documented error patterns, CLI command reference, production patterns (auth, middleware, storage), and async test templates

MCP Builder

Build a working MCP server from a description of the tools you need. Produces a deployable Python server using FastMCP.

Workflow

Step 1: Define What to Expose

Ask what the server needs to provide:

  • Tools -- Functions Claude can call (API wrappers, calculations, file operations)
  • Resources -- Data Claude can read (database records, config, documents)
  • Prompts -- Reusable prompt templates with parameters

A brief like "MCP server for querying our customer database" is enough.

Step 2: Scaffold the Server
