How to Set Up and Use Fly
FlyMCP is a lightweight MCP server written in Go that wraps the Fly.io CLI (flyctl) to expose Fly.io application management capabilities to Claude Desktop. It currently provides two tools: fly-logs for streaming application and machine-level logs, and fly-status for retrieving the JSON-formatted status of any Fly.io application. Developers who manage Fly.io deployments can use natural language with Claude Desktop to inspect app health and diagnose issues without manually running flyctl commands in a separate terminal.
Prerequisites
- Go 1.21 or higher installed (for building from source)
- flyctl CLI installed and authenticated via 'flyctl auth login'
- Claude Desktop installed and configured
- A Fly.io account with at least one deployed application
Clone the FlyMCP repository
Download the source code from GitHub. FlyMCP is distributed as source only and must be compiled locally.
git clone https://github.com/superfly/flymcp.git
cd flymcpDownload dependencies and build the binary
Fetch Go module dependencies and compile the flymcp binary into the current directory.
go mod download
go build -o flymcpAuthenticate with Fly.io
Ensure flyctl is authenticated before starting FlyMCP. The server invokes flyctl commands under your credentials.
flyctl auth loginConfigure Claude Desktop
Add FlyMCP to your claude_desktop_config.json using the absolute path to the compiled binary. The config file is at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.
Restart Claude Desktop
Quit and reopen Claude Desktop so it reads the updated config and spawns the FlyMCP server process.
Fly Examples
Client configuration
Add FlyMCP to claude_desktop_config.json using the absolute path to your compiled binary.
{
"mcpServers": {
"flymcp": {
"command": "/absolute/path/to/flymcp/flymcp",
"args": []
}
}
}Prompts to try
Use these prompts to inspect your Fly.io applications through Claude Desktop.
- "Show me the recent logs for my app named my-api"
- "What is the current status of the my-api application on Fly.io?"
- "Show logs for machine abc123 in my app my-worker"
- "Is my Fly.io app healthy? Check its status"
- "Get the latest logs from my Fly.io deployment"Troubleshooting Fly
fly-status or fly-logs returns 'command not found' for flyctl
Ensure flyctl is installed and on the PATH used by the Claude Desktop process. Run 'which flyctl' to find its location and add that directory to your system PATH, not just your shell PATH.
fly-logs returns an authentication error
Run 'flyctl auth login' in a terminal and complete the browser-based login flow. FlyMCP relies on the stored flyctl credentials, so the login must be completed before the server is started.
Claude Desktop does not detect the FlyMCP server after configuration
Use an absolute path (not a relative path) to the flymcp binary in claude_desktop_config.json. Run 'pwd' inside the flymcp directory after building to get the full path.
