Tiger GitHub MCP Server

A wrapper around the GitHub API to provide some focused tools to LLMs via the Model Context Protocol.

Development

Cloning and running the server locally.

git clone git@github.com:timescale/tiger-gh-mcp-server.git

Building

Run npm i to install dependencies and build the project. Use npm run watch to rebuild on changes.

You will need a GitHub token with the correct scopes. Here is a direct link to create such a new token.

Create a .env file based on the .env.sample file.

cp .env.sample .env

Then update the GITHUB_TOKEN value in .env.

VS Code Debugging

The project includes a VS Code debug profile called "Debug Github MCP" that:

1. Installs dependencies (npm i)

2. Builds the project (npm run build)

3. Launches the server in HTTP mode with full debugging support

To use it:

• Open the project in VS Code

• Go to the Debug panel (Ctrl/Cmd + Shift + D)

• Select "Debug Github MCP" from the dropdown

• Press F5 or click the play button

Breakpoints will work properly in TypeScript source files thanks to source map support.

Testing

The MCP Inspector is a very handy to exercise the MCP server from a web-based UI.

Testing in Claude Desktop

Create/edit the file ~/Library/Application Support/Claude/claude_desktop_config.json to add an entry like the following, making sure to use the absolute path to your local tiger-gh-mcp-server project, and use a valid GitHub token.

{
  "mcpServers": {
    "tiger-gh": {
      "command": "node",
      "args": ["/absolute/path/to/tiger-gh-mcp-server/dist/index.js", "stdio"],
      "env": {
        "GITHUB_TOKEN": "ghp_whatever",
        "GITHUB_ORG": "timescale"
      }
    }
  }
}
