This is a Model Context Protocol (MCP) server that fetches GitHub Pull Request comments using a GitHub personal access token.

Installation
Installing via Smithery
To install github-pr-mcp for Claude Desktop automatically via Smithery:

Installing Manually
Clone the repository
Install dependencies:
npm install
Create a .env file with your GitHub token:
GITHUB_TOKEN=your_github_token_here
Usage
Build the project:
npm run build
Run the server:
npm start
Or directly with a GitHub token:
node dist/server.js your_github_token_here
- The server exposes a tool called
get_pr_comments that accepts the following parameters:
* `owner`: Repository owner (username or organization)
* `repo`: Repository name
* `pull_number`: Pull request number
Integration with Cursor
To integrate with Cursor, use the following command in Cursor's MCP server configuration:
node /path/to/dist/server.js your_github_token_here
Replace /path/to with the actual path to your project, and your_github_token_here with your GitHub personal access token.
Testing
A test client is included to verify the server functionality:
Build the project:
npm run build
Run the test client:
npm test
The test client will start the server, connect to it, and call the get_pr_comments tool with sample parameters.
