In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Hevy MCPShow me my last 3 workouts and their details."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Hevy MCP
An MCP (Model Context Protocol) server for Hevy — the workout tracking app. Connects any MCP-compatible AI client (Claude, Cursor, etc.) to your Hevy account, letting it read your workouts, routines, and exercises, or log new ones on your behalf.
Built with FastMCP and async httpx.
Requirements
Python 3.11+
uv package manager
Hevy Pro subscription (for API access)
Hevy API key (Settings > API in the Hevy app)

Deployment
Docker (any platform)
Includes a Dockerfile for container deployment. The server reads PORT from the environment and exposes a /health_check endpoint.
docker build -t hevy-mcp .
docker run -e HEVY_API_KEY=your_key -e PORT=8080 hevy-mcpRailway
This project is set up for one-click deployment on Railway. See RAILWAY_DEPLOY.md for the full step-by-step playbook covering:
Creating the Railway project
Deploying the Docker container
Setting environment variables (
HEVY_API_KEY,ENVIRONMENT)Generating a public domain
Verifying the deployment (health check + MCP handshake)
The playbook documents the exact Railway MCP tool calls and parameters, so it can be followed manually or used as a reference for building an automated deployment skill with the Railway MCP server.
