Connect LLMs to Strava Data

Strava MCP Server

Talk to your Strava data using AI.

Connect Claude to your Strava account and ask questions in plain English: "How far did I run this month?", "Analyze my last ride", or "Show me my fastest segments."

What Can You Do With This?

Once connected, just talk to Claude like you're talking to a friend who has access to all your Strava data:

🏃 Track Your Progress

"How many kilometers did I run this month?"

"Compare my running stats from January to December"

"What's my longest ride ever?"

📊 Analyze Your Workouts

"Break down my last cycling workout - show me power, heart rate, and cadence"

"How did my heart rate zones look during yesterday's run?"

"What was my average pace for each lap in my interval training?"

🗺️ Explore Routes & Segments

"What are the most popular cycling segments near Central Park?"

"Show me my starred segments"

"Export my Sunday morning route as a GPX file"

🏆 Get Coaching Insights

"Analyze my training load this week"

"How does my current fitness compare to last month?"

"Give me a summary of my cycling performance this year"

Quick Start (3 Steps)

Step 1: Add to Claude Desktop

Open your Claude Desktop configuration file:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this to the file:

{
  "mcpServers": {
    "strava": {
      "command": "npx",
      "args": ["-y", "@r-huijts/strava-mcp-server"]
    }
  }
}

Step 1 (alternative): Add to Claude Code

You can add this MCP server to claude code with the following command:

claude mcp add --transport stdio strava -- npx @r-huijts/strava-mcp-server

You can confirm successful instalation as follows:

% claude mcp list
Checking MCP server health...

strava: npx @r-huijts/strava-mcp-server - ✓ Connected

Step 2: Restart Claude Desktop

Close and reopen Claude Desktop to load the new configuration.

Step 3: Connect Your Strava

Just say to Claude:

"Connect my Strava account"

A browser window will open. Enter your Strava API credentials, authorize the app, and you're done!

That's it! Start asking about your activities.

Connecting Your Strava Account

First Time Setup

When you say "Connect my Strava account", here's what happens:

1. A browser window opens showing a setup page
2. Enter your Strava API credentials (Client ID and Client Secret)
3. Click "Continue to Strava" - you'll be redirected to Strava
4. Authorize the app on Strava's website
5. See the success message - you can close the browser
6. Done! Claude confirms you're connected

Your credentials are saved locally at ~/.config/strava-mcp/config.json and persist across sessions.

Getting Your Strava API Credentials

You need to create a free Strava API application (one-time setup):

1. Go to strava.com/settings/api
2. Click "Create an App" (or view your existing app)
3. Fill in the form:
   • Application Name: Anything you want (e.g., "My Claude Assistant")
   • Category: Choose any
   • Website: Can be anything (e.g., http://localhost)
   • Authorization Callback Domain: Must be localhost
4. Copy your Client ID and Client Secret

That's it! You only need to do this once.

Managing Your Connection

• Check status: "Am I connected to Strava?"
• Reconnect: "Connect my Strava account" (use force: true to reconnect)
• Disconnect: "Disconnect my Strava account"

Installation Options

Option A: Just Use It (Recommended)

No installation needed! The npx command in the Quick Start automatically downloads and runs the latest version.

Option B: Install Globally

If you prefer to install it once:

npm install -g @r-huijts/strava-mcp-server

Then update your Claude config to use:

{
  "mcpServers": {
    "strava": {
      "command": "strava-mcp-server"
    }
  }
}

Note: Even though the package name is @r-huijts/strava-mcp-server, the executable name remains strava-mcp-server for backward compatibility.

Option C: Build from Source

For developers who want to modify the code:

git clone https://github.com/r-huijts/strava-mcp.git
cd strava-mcp
npm install
npm run build

Then point Claude to your local build:

{
  "mcpServers": {
    "strava": {
      "command": "node",
      "args": ["/path/to/strava-mcp/dist/server.js"]
    }
  }
}

Troubleshooting

"Connect my Strava account" doesn't open a browser

• Make sure Claude Desktop is running the MCP server (check for errors in Claude)
• Try restarting Claude Desktop
• Check that port 8111 isn't blocked by a firewall

"Authentication failed" or "Invalid token"

• Your token may have expired - say "Connect my Strava account" to reconnect
• Make sure your Strava API application is still active at strava.com/settings/api

"Missing credentials" error

• You need to complete the OAuth flow - say "Connect my Strava account"
• If you're using environment variables, make sure all 4 are set (see Developer section)

Claude doesn't see the Strava tools

• Make sure your claude_desktop_config.json is valid JSON (no trailing commas!)
• Restart Claude Desktop after making config changes
• Check Claude's developer console for error messages

JSONRPC.ProtocolTransportError after package name change

If you're getting a JSONRPC error after updating to @r-huijts/strava-mcp-server:

1. Clear npx cache: Run rm -rf ~/.npm/_npx in terminal
2. Verify config uses @r-huijts/strava-mcp-server (not the old strava-mcp-server)
3. Restart Claude Desktop completely (quit and reopen)
4. Test manually: Run npx -y @r-huijts/strava-mcp-server - you should see "Starting Strava MCP Server v1.2.1..."

For Developers
