# LMStudio-MCP
A Model Control Protocol (MCP) server that allows Claude to communicate with locally running LLM models via LM Studio.

## Overview
LMStudio-MCP creates a bridge between Claude (with MCP capabilities) and your locally running LM Studio instance. This allows Claude to:
- Check the health of your LM Studio API
- List available models
- Get the currently loaded model
- Generate completions using your local models
This enables you to leverage your own locally running models through Claude's interface, combining Claude's capabilities with your private models.
## Prerequisites
- Python 3.7+
- [LM Studio](https://lmstudio.ai/) installed and running locally with a model loaded
- Claude with MCP access
- Required Python packages (see Installation)
## 🚀 Quick Installation
### One-Line Install (Recommended)
```bash
curl -fsSL https://raw.githubusercontent.com/infinitimeless/LMStudio-MCP/main/install.sh | bash
```
### Manual Installation Methods
#### 1. Local Python Installation
```bash
git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP
pip install requests "mcp[cli]" openai
```
#### 2. Docker Installation
```bash
# 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
```
#### 3. Docker Compose
```bash
git clone https://github.com/infinitimeless/LMStudio-MCP.git
cd LMStudio-MCP
docker-compose up -d
```
For detailed deployment instructions, see [DOCKER.md](DOCKER.md).
## MCP Configuration
### Quick Setup
**Using GitHub directly (simplest)**:
```json
{
"lmstudio-mcp": {
"command": "uvx",
"args": [
"https://github.com/infinitimeless/LMStudio-MCP"
]
}
}
```
**Using local installation**:
```json
{
"lmstudio-mcp": {
"command": "/bin/bash",
"args": [
"-c",
"cd /path/to/LMStudio-MCP && source venv/bin/activate && python lmstudio_bridge.py"
]
}
}
```
**Using Docker**:
```json
{
"lmstudio-mcp-docker": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"--network=host",
"ghcr.io/infinitimeless/lmstudio-mcp:latest"
]
}
}
```
For complete MCP configuration instructions, see [MCP_CONFIGURATION.md](MCP_CONFIGURATION.md).
## Usage
1. **Start LM Studio** and ensure it's running on port 1234 (the default)
2. **Load a model** in LM Studio
3. **Configure Claude MCP** with one of the configurations above
4. **Connect to the MCP server** in Claude when prompted
## Available Functions
The bridge provides the following functions:
- `health_check()`: Verify if LM Studio API is accessible
- `list_models()`: Get a list of all available models in LM Studio
- `get_current_model()`: Identify which model is currently loaded
- `chat_completion(prompt, system_prompt, temperature, max_tokens)`: Generate text from your local model
## Deployment Options
This project supports multiple deployment methods:
| Method | Use Case | Pros | Cons |
|--------|----------|------|------|
| **Local Python** | Development, simple setup | Fast, direct control | Requires Python setup |
| **Docker** | Isolated environments | Clean, portable | Requires Docker |
| **Docker Compose** | Production deployments | Easy management | More complex setup |
| **Kubernetes** | Enterprise/scale | Highly scalable | Complex configuration |
| **GitHub Direct** | Zero setup | No local install needed | Requires internet |
## Known Limitations
- Some models (e.g., phi-3.5-mini-instruct_uncensored) may have compatibility issues
- The bridge currently uses only the OpenAI-compatible API endpoints of LM Studio
- Model responses will be limited by the capabilities of your locally loaded model
## Troubleshooting
### API Connection Issues
If Claude reports 404 errors when trying to connect to LM Studio:
- Ensure LM Studio is running and has a model loaded
- Check that LM Studio's server is running on port 1234
- Verify your firewall isn't blocking the connection
- Try using "127.0.0.1" instead of "localhost" in the API URL if issues persist
### Model Compatibility
If certain models don't work correctly:
- Some models might not fully support the OpenAI chat completions API format
- Try different parameter values (temperature, max_tokens) for problematic models
- Consider switching to a more compatible model if problems persist
