main

A set of project rules for a TypeScript server that generates Cursor coding rules. Cursor rules are instructions that guide an AI coding assistant inside a project.

In plain words
What is it for?
Understanding the server layout, its code-analysis and rule-generation modules, and the technologies used to build them.
Why use it?
It gives contributors shared guidance about the project’s structure, tools, and coding conventions. This reduces uncertainty when changing or extending the server.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

main 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 yesterday.

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.

Cursor Rules Generator - Development Guidelines

📁 Modular Structure: This project uses the official Cursor .cursor/rules/ format.

🎯 Quick Context

Project Type: MCP (Model Context Protocol) Server Primary Language: TypeScript Framework: Node.js with MCP SDK Purpose: Automatically generate cursor rules by analyzing codebases

📦 Tech Stack

  • Runtime: Node.js 18+
  • Language: TypeScript 5.x
  • MCP SDK: @modelcontextprotocol/sdk
  • File Operations: Node.js fs/promises
  • Git Integration: simple-git
  • Pattern Matching: glob

📝 Code Style

  • Use camelCase for functions and variables
  • Use PascalCase for types and interfaces
  • Use async/await for asynchronous operations
  • Export functions using named exports
  • Use ES modules (.js extensions in imports)

🔧 Key Patterns

  1. Analysis functions return typed interfaces from types.ts
  2. Template generators return formatted strings with MDC frontmatter
  3. MCP tools follow the SDK patterns for request/response handling
  4. File operations use fs/promises for async file I/O

🚀 Development Commands

npm run build     # Compile TypeScript
npm run dev       # Watch mode
npm start         # Run compiled server

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.

main is a cursor rule published in the GitHub repository ankitpro/cursor-rules-generator (6 stars, last pushed 5mo ago), licensed MIT. It adds 572 tokens to every session, about $0.0029 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
