Fly MCP Server

What is fly-mcp?

fly-mcp is an open-source MCP (Model Context Protocol) server for managing Fly.io infrastructure. It enables AI-driven DevOps workflows through natural language interactions, providing tools to list, inspect, restart, and scale Fly.io applications.

Set environment variables FLY_MCP_FLY_API_TOKEN and FLY_MCP_FLY_ORGANIZATION, then build and run the server with make build and make run (or make dev for hot reload).
