Nolio MCP Server

An MCP server that gives Claude read-only access to your Nolio training data — planned workouts, completed sessions, metrics, records, and notes.

Prerequisites

• Python 3.11+

• uv (recommended) or pip

• A Nolio API application (client ID + secret) — register at https://www.nolio.io/api/register/

Quick Start

1. Clone and install

git clone <repo-url> nolio-mcp
cd nolio-mcp
uv sync

2. Configure client credentials

Create a .env file with your Nolio client credentials:

cp .env.example .env
# Edit .env and fill in NOLIO_CLIENT_ID and NOLIO_CLIENT_SECRET

3. Authenticate with Nolio

Run the built-in OAuth helper to obtain your access and refresh tokens:

uv run nolio-auth

This opens your browser, you log into Nolio, and all credentials (client ID, client secret, access token, refresh token) are saved to ~/nolio-credentials.json.

Important: In your Nolio app settings, set the redirect URI to http://localhost:9876/callback.

4. Add to Claude Code

Since credentials are stored in ~/nolio-credentials.json, you don't need to pass environment variables:

claude mcp add nolio -- uv run --directory /path/to/nolio-mcp mcp run src/nolio_mcp/server.py

You can also re-authenticate at any time from within Claude Code by running /mcp and selecting the authenticate command on the nolio server, or directly via /mcp__nolio__authenticate.

4b. Or add to Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "nolio": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/nolio-mcp", "mcp", "run", "src/nolio_mcp/server.py"]
    }
  }
}

No env block needed — the server reads credentials from ~/nolio-credentials.json.

Available Tools

Most tools support optional from_date, to_date (YYYY-MM-DD), and limit parameters.

Available Prompts (Commands)

In Claude Code, run /mcp → select nolio → authenticate, or use /mcp__nolio__authenticate directly.

Development

Testing with the MCP Inspector

uv run mcp dev src/nolio_mcp/server.py

Running unit tests

uv run pytest tests/test_client.py

Running integration tests

Integration tests hit the real Nolio API. Set up credentials first:

cp .test-env.example .test-env
# Fill in .test-env with your Nolio dev credentials
uv run pytest tests/test_integration.py -m integration
