 Since MCP servers run over stdio, debugging can be challenging. For the best debugging
 experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).
 
-
 You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command:
 
 ```bash
-npx @modelcontextprotocol/inspector uv --directory /Users/markus/experiments/claude-mvp/mcp-knowledge-base run mcp-knowledge-base
+npx @modelcontextprotocol/inspector uv --directory /path/to/mcp-knowledge-base run mcp-knowledge-base
 ```
 
-
 Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
+
+You can also watch the server logs with this command:
+
+```bash
+tail -n 20 -f ~/Library/Logs/Claude/mcp-server-mcp-knowledge-base.log
