draftlytic-mcp

An MCP server that turns a rough project idea into a structured spec — right inside Claude Code, Cursor, or any MCP-compatible editor. No API key, no account, no network calls. It runs entirely on your machine and hands your editor's model a schema to write into, a checklist of what to ask about, a validator that catches gaps before you start coding, and a renderer that turns the result into a clean Markdown PRD.

This exists because "vibe coding" from a one-line prompt tends to produce a plausible-looking app that's missing half the decisions you actually needed to make — what's in scope for v1, what the data model looks like, what "done" means for a feature. draftlytic-mcp doesn't generate any of that for you; it structures the conversation so your model asks the right questions, then checks its own homework before you start building.

Install

Claude Code

claude mcp add draftlytic -- npx -y draftlytic-mcp

Cursor

Add to .cursor/mcp.json in your project (or the global ~/.cursor/mcp.json):

{
  "mcpServers": {
    "draftlytic": {
      "command": "npx",
      "args": ["-y", "draftlytic-mcp"]
    }
  }
}

Any other MCP client

Most MCP hosts read a generic mcp.json with the same shape:

{
  "mcpServers": {
    "draftlytic": {
      "command": "npx",
      "args": ["-y", "draftlytic-mcp"]
    }
  }
}

Usage

Once connected, ask your editor's model something like:

Use the plan_project prompt for "a habit tracker that reminds me by text message"

It'll walk through spec_checklist with you (platform, tech stack, audience, features, competitors, revenue, constraints, data model, notifications, external services, design & UX — a handful of concrete questions per category, many offered as click-to-pick single/multi-select choices rather than blank prompts, with a free-text escape always available), draft a spec, run it through validate_spec, fix what comes back, and hand you a rendered PRD in Markdown you can drop straight into a coding-agent prompt, a SPEC.md, or a GitHub issue.

You can also call the tools directly if you already have a spec drafted (by hand, or from another source) and just want it checked and rendered.
