prp-mcp-create

prp-mcp-create is a command for Claude Code from coleam00/context-engineering-intro. It costs 46 tokens per session (947 once invoked), scanned A, original, MIT.

A command that creates a PRP, or Product Requirement Prompt, for building a custom MCP server from a user’s description and existing project patterns.

In plain words
What is it for?
Use it to plan an MCP server with custom tools, GitHub OAuth, database integration, and Cloudflare Workers deployment.
Why use it?
It collects the requirements and relevant technical context needed before implementing an MCP server.

Command for Claude Code

About the project

Context Engineering Template is a repository of instructions, examples, workflows, and validation practices that give AI coding assistants the information they need to complete software tasks. It is for developers working with Claude Code or other coding assistants, and the catalogue entries package parts of its workflow as commands, agents, instructions, and a skill.

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

prp-mcp-create 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 6d 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.

Create MCP Server PRP

Create a comprehensive Product Requirement Prompt (PRP) for building Model Context Protocol (MCP) servers with authentication, database integration, and Cloudflare Workers deployment.

Before you start ensure that you read these key files to get an understanding about the goal of the PRP: PRPs/README.md PRPs/templates/prp_mcp_base.md (This base PRP is already partially filled out based on the project structure but please finish it specific to the user's use case for an MCP server)

Users MCP use case: $ARGUMENTS

Purpose

Generate context-rich PRPs specifically designed for MCP server development, using the proven patterns in this codebase that is a scaffolding of a MCP server setup that the user can build upon, including GitHub OAuth, and production-ready Cloudflare Workers deployment.

None of the existing tools will likely be reused and the tools should be created for the users use case specifically tailored to their needs.

Execution Process

  1. Research & Context Gathering

    • Create clear todos and spawn subagents to search the codebase for similar features/patterns Think hard and plan your approach
    • Gather relevant documentation about MCP tools, resources, and authentication flows
    • Research existing tool patterns to understand how to build the users specified use case
    • Study existing integration patterns in the codebase
  2. Generate Comprehensive PRP

    • Use the specialized PRPs/templates/prp_mcp_base.md template as the foundation
    • Customize the template with specific server requirements and functionality
    • Include all necessary context from the codebase patterns and ai_docs
    • Add specific validation loops for MCP server development
    • Include database integration patterns and security considerations
  3. Enhance with AI docs

    • The use might have added docs in PRPs/ai_docs/ directory that you should read
    • If there are docs in the PRPs/ai_docs/ directory, review them and take them into context as you build the PRP

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.
