 FastMCP includes a development server with the MCP Inspector for testing your server:
 
 ```bash
+# Basic usage
 fastmcp dev your_server.py
+
+# Load dependencies from current directory's pyproject.toml
+fastmcp dev your_server.py --uv-directory .
+
+# Install additional packages
+fastmcp dev your_server.py --with pandas,numpy
+
+# Combine both
+fastmcp dev your_server.py --uv-directory . --with pandas,numpy
 ```
 
+The `--with` flag automatically includes `fastmcp` and any additional packages you specify. The `--uv-directory` flag tells uv where to find your project's dependencies.
