[](https://smithery.ai/server/github-chat-mcp)
## Setup Instructions
> Before anything, ensure you have a GitHub Chat API key. This is required to use the service.
Install uv first.
MacOS/Linux:
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```
Windows:
```
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```
### Setup with Cursor (Recommended)
In mcp.json:
```json
{
"mcpServers": {
"github-chat": {
"command": "uvx",
"args": [
"github-chat-mcp"
]
}
}
}
```
With above, no envs required since it's a freemium release.
### Setup with Claude Desktop
```json
# 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": {
}
}
}
}
```
### Installing via Smithery
You can install GitHub Chat for Claude Desktop automatically via Smithery:
```bash
npx -y @smithery/cli install github-chat-mcp --client claude
```
### Using GitHub Chat with Claude
1. Index a GitHub repository first:
"Index the GitHub repository at https://github.com/username/repo"
2. Then ask questions about the repository:
"What is the core tech stack used in this repository?"
### Debugging
Run:
```bash
npx @modelcontextprotocol/inspector uvx github-chat-mcp
```
## Local/Dev Setup Instructions
### Clone repo
`git clone https://github.com/yourusername/github-chat-mcp.git`
### Install dependencies
Install uv first.
MacOS/Linux:
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```
Windows:
```
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```
Then install MCP server dependencies:
```bash

### Setup with Claude Desktop
#### Using MCP CLI SDK
```bash
# `pip install mcp[cli]` if you haven't

```
#### Manually
```json
# 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": {
}
}
}
}
```
### Using GitHub Chat with Claude
1. Index a GitHub repository first:
"Index the GitHub repository at https://github.com/username/repo"
2. Then ask questions about the repository:
"What is the core tech stack used in this repository?"
### Debugging
Run:
```bash
# 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`.
# Notes
- Level of logging is adjustable through the `FASTMCP_LOG_LEVEL` environment variable (e.g. `FASTMCP_LOG_LEVEL="ERROR"`)
- This MCP server provides two main tools:
1. Repository Indexing - Index and analyze a GitHub repository
2. Repository Querying - Ask questions about the indexed repository
