MCP, added to LM Studio 0.3.17, is an 'open standard for bidirectional connection between generative AI and other systems' announced by Anthropic in November 2024. By connecting to an MMCP server, the range of things that chat AI can do, such as information acquisition and automation, can be expanded by linking with external services and tools.

To add MCP to LM Studio, first open the chat screen and select 'Program' from the sidebar on the right.



Click “Install” and then click “Edit mcp.json”.



A warning about MCP was displayed. While MCP expands the range of things that AI can do, MCPs from untrusted sources can pose serious security risks. Therefore, it is important to be careful to 'use only trusted MCPs' and 'check operation properly.' Once you understand the warning, click 'Got It'.



An editor will open in the app, which you can edit to connect to any MCP server.



On

the page announcing LM Studio 0.3.17 , there is an example of how to connect to Hugging Face's MCP Server. Click 'Add to LM Studio'.



When I clicked on it in the browser, the following window opened in LM Studio. You can enter information by clicking 'Add'.



The 'Settings for connecting to the Hugging Face MCP server' were automatically written in the editor as shown below. By entering the token obtained from Hugging Face in the 'YOUR_HF_TOKEN' field shown in the red box below, the local LLM in LM Studio will be able to link with the tools and resources on Hugging Face.



The LM Studio 0.3.17 announcement page also includes a tool that creates a 'link button that allows you to connect to an MCP server on LM Studio with one click.'
