Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-gh-pr-mini CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is a minimal MCP (Model Context Protocol) server for GitHub pull request operations with dual authentication support. The project provides a focused set of tools for creating, listing, reviewing, and commenting on GitHub pull requests via MCP. It features a modular architecture with support for both Personal Access Token (PAT) and GitHub CLI authentication methods.

Key Commands

Development Commands

  • npm run build - Compile TypeScript to JavaScript and set executable permissions
  • npm test - Run the test suite
  • npm run test:watch - Run tests in watch mode
  • npm run test:coverage - Run tests with coverage report
  • npx mcp-gh-pr-mini - Run the built MCP server directly

Environment Setup

Authentication Methods (Auto-detected)
  1. GitHub CLI (Recommended): gh auth login
  2. Personal Access Token: Set GITHUB_PERSONAL_ACCESS_TOKEN environment variable
    • Required token permissions: Pull requests (read/write), Issues (read/write), Contents (read/write)
Debug Mode
  • Set DEBUG=true environment variable for detailed logging

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
