## 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:
```json
{
"mcpServers": {
"strava": {
"command": "npx",
"args": ["-y", "@r-huijts/strava-mcp-server"]
}
}
}
```
### 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](https://www.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:
```bash
npm install -g @r-huijts/strava-mcp-server
```
Then update your Claude config to use:
```json
{
"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:
```bash
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:
```json
{
"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](https://www.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
<details>
<summary>Click to expand technical details</summary>
### Environment Variables
Instead of using the browser-based auth, you can set environment variables:
| Variable | Description |
|----------|-------------|
| `STRAVA_CLIENT_ID` | Your Strava Application Client ID |
| `STRAVA_CLIENT_SECRET` | Your Strava Application Client Secret |
| `STRAVA_ACCESS_TOKEN` | OAuth access token |
| `STRAVA_REFRESH_TOKEN` | OAuth refresh token |
| `ROUTE_EXPORT_PATH` | Directory for GPX/TCX exports |
### Token Refresh
The server automatically refreshes expired tokens. New tokens are saved to both `process.env` and `~/.config/strava-mcp/config.json`.
### Config Priority
1. Environment variables (highest)
2. `~/.config/strava-mcp/config.json`
3. Local `.env` file
### Building & Testing
```bash
npm install
npm run build
npm test
```
### Activity Streams Optimization
The `get-activity-streams` tool uses a compact format by default, reducing payload size by ~70-80% while preserving all data:
- **Compact format** (default): Raw arrays with metadata, ~70-80% smaller, ideal for LLM processing
- **Verbose format**: Human-readable objects with formatted values (backward compatible)
- **Smart chunking**: Large activities automatically split into ~50KB chunks
- **Optional downsampling**: Can reduce very large datasets while preserving key features
The compact format includes comprehensive metadata (units, descriptions, statistics) so LLMs can understand the raw numeric data.
### API Reference
The server implements the Model Context Protocol (MCP) and exposes 24 tools for Strava API v3. See the source code in `src/tools/` for implementation details.
