Verify installation: `pip list | grep my-mcp-server` 2. Reinstall: `pip install --force-reinstall my-mcp-server` 3. Check Python version: `python --version` (requires 3.11+) ### Node.js: Command not found **Problem**: `command not found: my-mcp-server` **Solution**: 1. Verify installation: `npm list -g my-mcp-server` 2. Check npm bin path: `npm bin -g` 3. Reinstall: `npm install -g my-mcp-server` ## Configuration Issues ### Claude Desktop not detecting server **Problem**: Server doesn't appear in Claude Desktop **Solutions**: 1. Check config file location (see Installation section) 2. Validate JSON syntax: use [jsonlint.com](https://jsonlint.com) 3. Restart Claude Desktop completely 4. Check server starts manually: `my-mcp-server` ### Environment variables not loading **Problem**: API calls failing with "missing API key" **Solutions**: 1. Verify `.env` file exists and has correct format 2. Check variable names match exactly 3. For Claude Desktop, add variables to `env` section in config 4. Restart server after changing environment variables ## Runtime Issues ### Server crashes on startup **Problem**: Server exits immediately **Steps**: 1. Run server manually to see errors: ```bash my-mcp-server ``` 2. Check logs in Claude Desktop logs directory 3. Verify all dependencies installed 4. Check for port conflicts (SSE servers) ### Tools fail with "timeout" **Problem**: Tool calls timeout **Solutions**: 1. Check network connectivity 2. Verify API endpoints are accessible 3. Increase timeout values in configuration 4. Check server logs for specific errors ### High memory usage **Problem**: Server using excessive memory **Solutions**: 1. Check for resource leaks (unclosed connections) 2. Implement resource caching with limits 3. Add pagination for large datasets 4. Restart server periodically if needed ## Debugging ### Enable debug logging **Claude Desktop config:** ```json { "mcpServers": { "my-server": { "command": "my-mcp-server", "env": { "LOG_LEVEL": "debug" } } } } ``` ### Check server logs **macOS:** ```bash tail -f ~/Library/Logs/Claude/mcp-server-my-mcp-server.log ``` **Linux:** ```bash tail -f ~/.config/Claude/logs/mcp-server-my-mcp-server.log ``` ### Test server independently ```bash # Python python -m my_mcp_server # Node.js node build/index.js # With MCP Inspector mcp-inspector python -m my_mcp_server ``` ## Getting Help 1.
