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
- 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 | shWindows:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
In mcp.json:
{
"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 at https://github.com/username/repo"
-
Then ask questions about the repository: "What is the core tech stack used in this repository?"
Run:
npx @modelcontextprotocol/inspector uvx github-chat-mcp
git clone https://github.com/yourusername/github-chat-mcp.git
Install uv first.
MacOS/Linux:
curl -LsSf https://astral.sh/uv/install.sh | shWindows:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
Then install MCP server dependencies:
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 at https://github.com/username/repo"
-
Then ask questions about the repository: "What is the core tech stack used in this repository?"
Run:
# 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 at http://localhost:5173. You may need to add your GitHub API key in the environment variables in the inspector under GITHUB_API_KEY.
- Level of logging is adjustable through the
FASTMCP_LOG_LEVELenvironment variable (e.g.FASTMCP_LOG_LEVEL="ERROR") - This MCP server provides two main tools:
- Repository Indexing - Index and analyze a GitHub repository
- Repository Querying - Ask questions about the indexed repository
