mcpserver CLAUDE.md

mcpserver CLAUDE.md is an instructions file for coding agents from pietrodelfranco/mcpserver. It costs 5,279 tokens per session, scanned A, a copy of remote-mcp-server-with-auth CLAUDE.md, MIT.

A set of Claude Code instructions for building an MCP server with GitHub sign-in, using Node.js, TypeScript, and Cloudflare Workers. GitHub OAuth is a way to let users sign in through GitHub.

In plain words
What is it for?
Developing and maintaining an MCP server with GitHub OAuth, npm, and Cloudflare Workers.
Why use it?
It gives coding agents project rules and implementation guidance, reducing uncertainty about authentication, simplicity, and code structure.

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

mcpserver 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 4d 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.

Origin

This is a copy

100% identical to remote-mcp-server-with-auth CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MCP Server with GitHub OAuth - Implementation Guide

This guide provides implementation patterns and standards for building MCP (Model Context Protocol) servers with GitHub OAuth authentication using Node.js, TypeScript, and Cloudflare Workers. For WHAT to build, see the PRP (Product Requirement Prompt) documents.

Core Principles

IMPORTANT: You MUST follow these principles in all code changes and PRP generations:

KISS (Keep It Simple, Stupid)

  • Simplicity should be a key goal in design
  • Choose straightforward solutions over complex ones whenever possible
  • Simple solutions are easier to understand, maintain, and debug

YAGNI (You Aren't Gonna Need It)

  • Avoid building functionality on speculation
  • Implement features only when they are needed, not when you anticipate they might be useful in the future

Open/Closed Principle

  • Software entities should be open for extension but closed for modification
  • Design systems so that new functionality can be added with minimal changes to existing code

Package Management & Tooling

CRITICAL: This project uses npm for Node.js package management and Wrangler CLI for Cloudflare Workers development.

Essential npm Commands

# Install dependencies from package.json
npm install

# Add a dependency
npm install package-name

# Add a development dependency
npm install --save-dev package-name

# Remove a package
npm uninstall package-name

# Update dependencies
npm update

# Run scripts defined in package.json
npm run dev
npm run deploy
npm run type-check

Essential Wrangler CLI Commands

CRITICAL: Use Wrangler CLI for all Cloudflare Workers development, testing, and deployment.

# Authentication
wrangler login          # Login to Cloudflare account
wrangler logout         # Logout from Cloudflare
wrangler whoami         # Check current user

# Development & Testing
wrangler dev           # Start local development server (default port 8787)

# Deployment
wrangler deploy        # Deploy Worker to Cloudflare
wrangler deploy --dry-run  # Test deployment without actually deploying

# Configuration & Types
wrangler types         # Generate TypeScript types from Worker configuration

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.
