hevy-mcp-remote: Hosted / gateway-ready MCP for Hevy Fitness
Fork notice. This is an independently-maintained fork of chrisdoc/hevy-mcp, repackaged for multi-tenant MCP gateways. It ships the same Hevy tools wrapped in supergateway as an OCI image that speaks MCP streamable-HTTP over HTTP, instead of stdio. Use the upstream hevy-mcp npm package for local/stdio use in Claude Desktop, Cursor, etc.
A Model Context Protocol (MCP) server for the Hevy fitness tracking app, packaged as a supergateway-wrapped OCI image for hosting behind an MCP gateway. Exposes MCP streamable-HTTP on /mcp and health on /healthz; reads HEVY_API_KEY from the container environment.

🏁 Quick Start
Pick the workflow that fits your setup:
| Scenario | Command | Requirements |
|---|
| One-off stdio run | HEVY_API_KEY=sk_live... npx -y hevy-mcp | Node.js ≥ 24, Hevy API key |
| Local development | npm install && npm run build && npm start | .env with HEVY_API_KEY |
🛠️ Prerequisites
- Node.js: v24 or higher (strongly recommended to use the exact version pinned in
.nvmrc).
- npm: v10 or higher.
- Hevy API key: Required for all operations (available with Hevy PRO).
📦 Installation
Run via npx (Recommended)
You can launch the server directly without cloning:
HEVY_API_KEY=your_hevy_api_key_here npx -y hevy-mcp
Manual Installation
git clone https://github.com/chrisdoc/hevy-mcp.git
cd hevy-mcp
npm install
cp .env.sample .env
🔗 Integration
Claude Desktop Configuration
To use this server with Claude Desktop, add the following to your claude_desktop_config.json:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"hevy-mcp": {
"command": "npx",
"args": ["-y", "hevy-mcp"],
"env": {
"HEVY_API_KEY": "sk_live_your_key_here"
}
}
}
}
Cursor Configuration
Add this server under "mcpServers" in ~/.cursor/mcp.json:
{
"mcpServers": {
"hevy-mcp": {
"command": "npx",
"args": ["-y", "hevy-mcp"],
"env": {
"HEVY_API_KEY": "your-api-key-here"
}
}
}
}
✨ Why hevy-mcp?
- 🚀 High Performance: Built with the Oxc toolchain (
oxlint/oxfmt) for near-instant linting and formatting.
- 🛡️ Type Safety: Fully type-safe implementation using Zod and Kubb-generated API clients.
- 📉 Observability: Built-in Sentry monitoring for error tracking and performance profiling.
- ⚡ Optimized: Includes in-memory caching for exercise templates to reduce API latency.
⚙️ Configuration
Supply your Hevy API key via:
- Environment Variable:
HEVY_API_KEY (in .env or system environment).
- CLI Argument:
--hevy-api-key=your_key (after -- in npm scripts).
# Example .env
HEVY_API_KEY=your_hevy_api_key_here
📡 Sentry Monitoring
hevy-mcp includes Sentry monitoring to observe errors and usage in production. It initializes @sentry/node with tracing enabled and PII collection disabled by default.
🐳 Running behind an MCP gateway (supergateway contract)
The MCP server itself speaks stdio only. For multi-tenant gateway
deployments (e.g. mcp-gateway-poc),
this repo ships a Dockerfile that wraps the stdio binary with
supergateway so a single
container exposes MCP streamable-HTTP.
The image follows the same contract every gateway-hosted MCP uses:
- MCP streamable-HTTP on
0.0.0.0:$PORT at /mcp
- Health endpoint at
/healthz
- Stateful sessions (
Mcp-Session-Id honored)
HEVY_API_KEY is read from the container environment and passed to the
spawned stdio child
Images are published to ghcr.io/rwestergren/hevy-mcp from main and from
any manually cut GitHub release. Build locally with:
docker build -t hevy-mcp:local .
docker run --rm -e HEVY_API_KEY=sk_live_... -p 8080:8080 hevy-mcp:local
curl http://localhost:8080/healthz
End users running hevy-mcp directly should use the stdio/npx flow above;
the Docker image is aimed at gateway operators, not individual clients.
