Architecture

Claude Desktop ←→ LibreModel MCP Server ←→ llama-server API ←→ LibreModel (Gigi)

The MCP server acts as a bridge, translating MCP protocol messages into llama-server API calls and formatting responses for Claude Desktop.

Troubleshooting

"Cannot reach LibreModel server"

• Ensure llama-server is running on the configured port
• Check that the model is loaded and responding
• Verify firewall/network settings

"Tool not found in Claude Desktop"

• Restart Claude Desktop after configuration changes
• Check that the path to index.js is correct and absolute
• Verify the MCP server builds without errors

Poor response quality

• Adjust temperature and sampling parameters
• Try different system prompts
• Check if LibreModel needs more training
