⇱ Connect LM Studio to Antigravity IDE Using MCP - DEV Community

I wanted to use my local LM Studio models inside Antigravity IDE, so I connected them through MCP.

from jervi-writes blog

Requirements

  • Antigravity IDE
  • LM Studio
  • A loaded model (Gemma, Qwen, Llama, etc.)
  • uv installed, if not then do install it with following brew install uv

Start the LM Studio server:

Developer → Local Server

Default endpoint:

http://127.0.0.1:1234/v1

Method 1: Using uvx (Recommended)

Add this to your Antigravity MCP config:

{"mcpServers":{"lmstudio-mcp":{"type":"stdio","command":"uvx","args":["git+https://github.com/infinitimeless/LMStudio-MCP"],"env":{"LMSTUDIO_HOST":"127.0.0.1","LMSTUDIO_PORT":"1234"}}}}

Important: Use git+https://, otherwise you'll get:

Direct URL references a Git repository,
but is missing the git+ prefix

Reload Antigravity.

Method 2: Clone Locally 

git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP

python3 -m venv venv
source venv/bin/activate

pip install requests "mcp[cli]" openai

MCP config:

{"mcpServers":{"lmstudio-mcp":{"type":"stdio","command":"/bin/bash","args":["-c","cd ~/LMStudio-MCP && source venv/bin/activate && python lmstudio_bridge.py"]}}}

Reload Antigravity.

Test

Ask:

Use lmstudio-mcp health_check

Or:

Use lmstudio-mcp to explain this file

How It Works 

Antigravity
 ↓
MCP Bridge
 ↓
LM Studio
 ↓
Local Model

This does not replace Antigravity's main model.

It gives Antigravity access to your local model as an MCP tool, allowing you to use Gemma, Qwen, Llama, DeepSeek, or any model loaded in LM Studio.
