Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
GitHub Chat MCPCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
pip install github-chat-mcp
uv install github-chat-mcp
3. Start using it with Claude!
Example prompts:
- "Use github-chat-mcp to analyze the React repository"
- "Index the TypeScript repository with github-chat-mcp and ask about its architecture"
> Before anything, ensure you have a GitHub Chat API key. This is required to use the service.
Install uv first.
MacOS/Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

}A Model Context Protocol (MCP) for analyzing and querying GitHub repositories using the GitHub Chat API. Official Site:https://github-chat.com
# Install with pip pip install github-chat-mcp # Or install with the newer uv package manager uv install github-chat-mcp
- "Use github-chat-mcp to analyze the React repository"
- "Index the TypeScript repository with github-chat-mcp and ask about its architecture"
Before anything, ensure you have a GitHub Chat API key. This is required to use the service.
curl -LsSf https://astral.sh/uv/install.sh | sh
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
{ "mcpServers": { "github-chat": { "command": "uvx", "args": [ "github-chat-mcp" ] } } }
With above, no envs required since it's a freemium release.
# claude_desktop_config.json # Can find location through: # Hamburger Menu -> File -> Settings -> Developer -> Edit Config # Must perform: brew install uv { "mcpServers": { "github-chat": { "command": "uvx", "args": ["github-chat-mcp"], "env": { } } } }
You can install GitHub Chat for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install github-chat-mcp --client claude
-
Index a GitHub repository first: "Index the GitHub repository athttps://github.com/username/repo"
Then ask questions about the repository: "What is the core tech stack used in this repository?"
npx @modelcontextprotocol/inspector uvx github-chat-mcp
git clone https://github.com/yourusername/github-chat-mcp.git
curl -LsSf https://astral.sh/uv/install.sh | sh
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
cd github-chat-mcp # Create virtual environment and activate it uv venv source .venv/bin/activate # MacOS/Linux # OR .venv/Scripts/activate # Windows # Install dependencies uv sync
# pip install mcp[cli] if you haven't mcp install /ABSOLUTE/PATH/TO/PARENT/FOLDER/github-chat-mcp/src/github_chat_mcp/server.py -v "GITHUB_API_KEY=API_KEY_HERE"
# claude_desktop_config.json # Can find location through: # Hamburger Menu -> File -> Settings -> Developer -> Edit Config { "mcpServers": { "github-chat": { "command": "uv", "args": [ "--directory", "/ABSOLUTE/PATH/TO/PARENT/FOLDER/github-chat-mcp", "run", "github-chat-mcp" ], "env": { } } } }

Index a GitHub repository first: "Index the GitHub repository athttps://github.com/username/repo"
Then ask questions about the repository: "What is the core tech stack used in this repository?"
# If mcp cli installed (pip install mcp[cli]) mcp dev /ABSOLUTE/PATH/TO/PARENT/FOLDER/github-chat-mcp/src/github_chat_mcp/server.py # If not npx @modelcontextprotocol/inspector \ uv \ --directory /ABSOLUTE/PATH/TO/PARENT/FOLDER/github-chat-mcp \ run \ github-chat-mcp
Then access MCP Inspector athttp://localhost:5173. You may need to add your GitHub API key in the environment variables in the inspector underGITHUB_API_KEY.
