LMStudio-MCP serves as a bridge between Claude (with Model Control Protocol capabilities) and your locally running LM Studio instance. This allows Claude to interact with your local LLM models, checking their health, listing available models, and generating completions using your private local models rather than Claude's default models.
The fastest way to install LMStudio-MCP is with the one-line installer:
curl -fsSL https://raw.githubusercontent.com/infinitimeless/LMStudio-MCP/main/install.sh | bash
git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP
pip install requests "mcp[cli]" openai
# Using pre-built image
docker run -it --network host ghcr.io/infinitimeless/lmstudio-mcp:latest
# Or build locally
git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP
docker build -t lmstudio-mcp .
docker run -it --network host lmstudio-mcp
git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP
docker-compose up -d

The bridge provides several functions that Claude can use to interact with your local models:
health_check()
: Verify if LM Studio API is accessiblelist_models()
: Get a list of all available models in LM Studioget_current_model()
: Identify which model is currently loadedchat_completion(prompt, system_prompt, temperature, max_tokens)
: Generate text from your local modelIf Claude reports 404 errors when trying to connect to LM Studio:
If certain models don't work correctly:
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "lmstudio-mcp" '{"command":"uvx","args":["https://github.com/infinitimeless/LMStudio-MCP"]}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"lmstudio-mcp": {
"command": "uvx",
"args": [
"https://github.com/infinitimeless/LMStudio-MCP"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"lmstudio-mcp": {
"command": "uvx",
"args": [
"https://github.com/infinitimeless/LMStudio-MCP"
]
}
}
}
3. Restart Claude Desktop for the changes to take effect
