[](https://smithery.ai/server/github-mapper-mcp-server)
GitHub Mapper is a Model Context Protocol (MCP) server that provides tools for mapping and analyzing GitHub repositories. It allows users to set a GitHub Personal Access Token and retrieve detailed information about a specified repository, including its structure and summary statistics.
## Features
- Set GitHub Personal Access Token for authentication
- Map and analyze GitHub repository structure
- Retrieve repository summary information (stars, forks, language, etc.)
- Provide a detailed repository file structure
## Prerequisites
- Node.js (v18.0.0 or later recommended)
- npm (comes with Node.js)
- A GitHub Personal Access Token with appropriate permissions

## Running evals
The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found [here](https://www.mcpevals.io/docs).
```bash
OPENAI_API_KEY=your-key npx mcp-eval src/evals/evals.ts src/index.ts
```
## Error Handling
- If the GitHub token is not set, you'll receive an error message prompting you to use the `set-github-token` tool first.
- Invalid GitHub URLs or repository paths will result in appropriate error messages.
