GitHub Issues Server

An MCP (Model Context Protocol) server for discovering and triaging open-source GitHub issues — built by hand, connected to Claude Desktop, and used to find good-fit issues to contribute to (SGLang, vLLM, and beyond).

Features

• fetch_issue(repo, issue_number) — Get details of a single issue: title, body, state, comments, labels, and whether it's a PR.
• list_issues(repo, state, labels, sort, direction, include_prs) — Fetch and filter a repo's issues by state, labels, and sort order (up to 100 per call).
• find_related_prs(repo, issue_number) — Checks an issue's timeline for linked pull requests, and reports whether any are open or merged.

Setup

1. Install dependencies:

   pip install -r requirements.txt
   

2. Create a .env file in the project root:

   GITHUB_TOKEN=your_personal_access_token
   

   Generate a token at GitHub → Settings → Developer settings → Personal access tokens (read-only, public_repo scope is enough).

3. Test locally with the MCP inspector:

   mcp dev server.py
   

Connecting to Claude Desktop

Add the server to Claude Desktop's MCP config (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "github-issues": {
      "command": "uv",
      "args": ["run", "--with", "mcp", "mcp", "run", "/absolute/path/to/server.py"]
    }
  }
}

Fully quit and reopen Claude Desktop. Once connected, you can ask things like:

"Find open good first issues in sgl-project/sglang"

and Claude will call the tools directly and return live results.

Notes

• Uses the GitHub REST API with a personal access token (free, 5,000 requests/hour authenticated).
• Rate limiting and deep error handling are intentionally out of scope for this version — basic status code checks only (200 / 404 / 401 / other).
• find_related_prs relies on the issue timeline endpoint's cross-referenced events; issues closed manually (without a linked PR) will correctly show no linked PR.
