# Testing Stats Compass Remote MCP Server
## Current Status
✅ **Server is running and operational at http://localhost:8000**
The server has been successfully tested with:
- HTTP connectivity test (✅ responds on port 8000)
- MCP protocol enforcement (✅ properly requires session ID)
- All 26 tools registered and loaded
## Quick Test
Server is already running in background. Test it:
```bash
cd /Users/tunjiogunbiyi/Dev/stats-compass-mcp
poetry run python test_server.py
```
Expected output:
```
✅ Server is running!
Status: 400
Response: {"jsonrpc":"2.0","id":"server-error","error":{"code":-32600,"message":"Bad Request: Missing session ID"}}
✅ Server is properly enforcing MCP protocol!
```
## Start/Stop Server
### Start server in background:
```bash
cd /Users/tunjiogunbiyi/Dev/stats-compass-mcp
nohup poetry run stats-compass-remote > server.log 2>&1 &
```
### Check if server is running:
```bash
ps aux | grep stats-compass-remote
# or
curl -s http://localhost:8000/mcp | jq
```
### Stop server:
```bash
pkill -f stats-compass-remote
```
### View logs:
```bash
tail -f /Users/tunjiogunbiyi/Dev/stats-compass-mcp/server.log
```
## Test with Claude Desktop
### Option 1: HTTP Remote Server (Current Setup)
The server is running at `http://localhost:8000` and can be tested via HTTP.
**Note:** FastMCP HTTP/SSE transport is not yet officially supported by Claude Desktop, which expects stdio transport. The server works via HTTP but Claude Desktop integration requires additional configuration.
### Option 2: Local stdio Server (Already Configured)
You already have the local version configured in Claude Desktop:
```json
{
"mcpServers": {
"stats-compass": {
"command": "/Users/tunjiogunbiyi/Library/Caches/pypoetry/virtualenvs/stats-compass-mcp-lbXH-2y2-py3.12/bin/stats-compass-mcp",
"args": ["serve"]
}
}
}
```
This runs the stdio version (`stats-compass-mcp serve`) which works with Claude Desktop.

## Next Steps
1. ✅ **Server operational** - Already running and tested
2. ⏳ **Claude Desktop integration** - Requires stdio transport adapter or FastMCP update
3. ⏳ **Docker deployment** - Dockerfile ready, needs Docker Desktop to test
4. ⏳ **S3 storage** - S3StorageBackend implemented, needs AWS credentials to test
5. ⏳ **Load testing** - Test session limits (max 100 sessions, 24h TTL)
6. ⏳ **Production deployment** - Deploy to cloud platform (AWS, Render, Railway, etc.)
