DICOM MCP Server - Installation Instructions (Linux)

1. Move this entire folder to your preferred location, e.g.:
   /opt/dicom_mcp_standalone_linux_${DIST_ARCH}

2. Edit your MCP client configuration file to add this server.

   For Claude Desktop on Linux (~/.config/Claude/claude_desktop_config.json):

   {
     "mcpServers": {
       "dicom_mcp": {
         "command": "/path/to/dicom_mcp_standalone_linux_${DIST_ARCH}/run_dicom_mcp.sh"
       }
     }
   }

   (Replace /path/to/ with the actual location where you placed this folder)

3. Restart your MCP client

4. Verify the server is working by asking Claude:
   "List available MCP tools"

You should see 12 DICOM tools available.

No Python installation required - everything is bundled!
