Puregym

puregym-mcp is a Python package and Model Context Protocol server for browsing PureGym centers in Denmark, discovering classes, checking your bookings, and managing bookings from MCP-compatible clients.

This is an independent third-party project and is not affiliated with, endorsed by, or sponsored by PureGym. PureGym is a registered trademark of Pure Gym Limited.

• Docs: puregym-mcp.jorgesintes.dev
• Public read-only endpoint: https://puregym-mcp.jorgesintes.dev/mcp
• PyPI: puregym-mcp

Capabilities

The server exposes a small set of tools for public class discovery and optional authenticated booking actions.

Class discovery

Available without PureGym credentials:

• get_capabilities
• list_class_types
• list_centers
• search_classes

Booking management

Available when PUREGYM_USERNAME and PUREGYM_PASSWORD are configured:

• list_my_bookings
• book_class
• cancel_booking
• get_center_live_status - Real-time occupancy and capacity data
• get_center_open_hours - Opening and staffed hours for a center

Modes

• Anonymous mode exposes read-only tools and uses a 14-day search window.
• Authenticated mode unlocks booking tools and expands the default search window to 28 days.

Authentication for HTTP Transports

When running over streamable-http or sse transports, the server requires Bearer token authentication in addition to PureGym credentials. This prevents unauthorized access to your booking capabilities when exposing the MCP server remotely.

Required environment variables for HTTP transports:

• PUREGYM_USERNAME - Your PureGym account email
• PUREGYM_PASSWORD - Your PureGym account password
• MCP_AUTH_TOKEN - A secret Bearer token you choose (e.g., a random string)

Note: stdio transport requires no authentication and runs unauthenticated by default.

Connect from MCP clients (e.g., Mistral) using Simple Auth / HTTP Bearer Token with your MCP_AUTH_TOKEN.

Quickstart

For most users, the easiest setup is local stdio usage from an MCP-compatible client:

{
  "mcp": {
    "puregym": {
      "enabled": true,
      "type": "local",
      "command": ["uvx", "puregym-mcp"],
      "environment": {
        "PUREGYM_USERNAME": "your-username",
        "PUREGYM_PASSWORD": "your-password"
      }
    }
  }
}

The environment block is optional and only needed for authenticated features.

Remote Deployment

The server supports both streamable-http and sse for remote MCP clients.

Bearer Token Authentication

HTTP transports (streamable-http, sse) require Bearer token authentication to protect your booking capabilities:

export PUREGYM_USERNAME="[email protected]"
export PUREGYM_PASSWORD="your-password"
export MCP_AUTH_TOKEN="your-secret-bearer-token"

puregym-mcp --transport streamable-http --host 0.0.0.0 --port 8000 --streamable-http-path /mcp

Connect from MCP clients using Simple Auth or HTTP Bearer Token authentication with your MCP_AUTH_TOKEN.

Docker Compose Example

services:
  puregym-mcp:
    image: puregym-mcp
    environment:
      - PUREGYM_USERNAME=${PUREGYM_USERNAME}
      - PUREGYM_PASSWORD=${PUREGYM_PASSWORD}
      - MCP_AUTH_TOKEN=${MCP_AUTH_TOKEN}
    ports:
      - "8000:8000"
    command:
      - --transport
      - streamable-http
      - --host
      - 0.0.0.0
      - --port
      - "8000"
      - --streamable-http-path
      - /mcp

Store sensitive values in a .env file (never commit this file):

[email protected]
PUREGYM_PASSWORD=your-password
MCP_AUTH_TOKEN=your-secret-bearer-token-min-16-chars-recommended

Public Read-Only Hosting

• Hosted endpoint: https://puregym-mcp.jorgesintes.dev/mcp
• Runs in anonymous mode (no booking capabilities)
• Use this for public class discovery only

Python Library

The package also exposes a reusable client and service layer:

from puregym_mcp import PureGymClient, PureGymService

# Anonymous client
client = PureGymClient()

# Authenticated client with custom timeout
client = PureGymClient(
    username="your-username",
    password="your-password",
    timeout=30.0  # seconds
)

service = PureGymService(client)

# Book and cancel return typed results
result = await service.book_class(booking_id, activity_id, payment_type)
print(result.participation_id)  # snake_case field

cancel_result = await service.cancel_booking(participation_id)
print(cancel_result.status)

Docker

Build the image:

docker build -t puregym-mcp .

Run a public read-only server:

docker run --rm -p 8000:8000 puregym-mcp

Run a private authenticated server (HTTP transport with Bearer token auth):

docker run --rm -p 8000:8000 \
  -e PUREGYM_USERNAME=your-email \
  -e PUREGYM_PASSWORD=your-password \
  -e MCP_AUTH_TOKEN=your-secret-token \
  puregym-mcp

Override the default container transport or path when needed:

docker run --rm -p 8000:8000 puregym-mcp \
  --transport sse \
  --host 0.0.0.0 \
  --port 8000 \
  --sse-path /sse

Development

Clone the repo and install dev dependencies:

uv sync --dev

Run from source:

uv run puregym-mcp --transport stdio

Run checks:

uv run pytest
uv run python -m compileall puregym_mcp tests
uv build

Test the built package locally before publishing:

uvx --from dist/puregym_mcp-0.3.0-py3-none-any.whl puregym-mcp --transport stdio

Run real API integration tests (requires credentials):

PUREGYM_USERNAME=your-username PUREGYM_PASSWORD=your-password uv run pytest tests/real_api -m real_api

MCP Inspector

Launch the Inspector against this repo:

npx @modelcontextprotocol/inspector \
  uv \
  --directory /path/to/puregym-mcp \
  run \
  puregym-mcp --transport stdio

Launch it in authenticated mode:

npx @modelcontextprotocol/inspector \
  -e PUREGYM_USERNAME=your-email \
  -e PUREGYM_PASSWORD=your-password \
  -- \
  uv \
  --directory /path/to/puregym-mcp \
  run \
  puregym-mcp --transport stdio

The Inspector UI opens at http://localhost:6274.
