PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • search_prompts

    Search the Builder's Prompt Library (3,323 rubric-graded prompts for software delivery) by keyword. Optionally filter by delivery stage or prompt-writing grade. Returns ranked matches with slug, title, summary, stage, category, and grade. Grades and quality_score describe prompt

  • get_prompt

    Fetch the full text and metadata of a single published prompt by its slug, including where it runs (any chat app, chat app with your code pasted in, a tool with web access, or a coding agent).

  • list_stages

    List the six delivery stages in the Builder's Prompt Library and how many published prompts each contains.

Common questions

Is The Builder's Prompt Library safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

The Builder's Prompt Library, as data

3,323 rubric-graded AI prompts for every stage of shipping software, from idea to launch. This is the open data behind buildersprompt.com, exported from the live catalog so you can grep it, vendor it, load it into your own tools, or point an agent at it.

Built by Alicia Dahling and Peter Lowe. Free to read, copy and adapt under CC BY 4.0 (see LICENSE): keep the attribution, do what you like with the prompts.

What is in here

PathWhat it is
data/prompts.jsonEvery published prompt as one JSON array (title, summary, stage, category, difficulty, tags, variables, tips, prompt text, writing score and grade, hand-reviewed flag, canonical URL).
data/by-stage/*.jsonThe same rows split by delivery stage: idea, design, build, test, secure, ship.
data/index.tsvOne line per prompt: stage, category, grade, score, slug, title. Good for grep and awk.
prompts/ / .mdOne Markdown file per prompt with YAML front matter, for editors, static-site generators and retrieval pipelines.

Fill-in fields look like {{project_name}}. Replace them before you paste.

How the grades work

Every prompt is scored 0 to 100 on a five-part writing rubric (clarity, specificity, format, variables, actionability) and stamped A+ (90+), A (80 to 89), B (70 to 79) or C (60 to 69). Anything below 60 is not published. The grade describes how well the prompt is written, not how well a model answered it. Prompts that were actually run in ChatGPT, Claude and Gemini, with the graded answers, are shown on their pages at buildersprompt.com under "Tested in real AI models". Twenty-two prompts were read line by line by a human and carry hand_reviewed: true.

Use it from an AI assistant instead

The library is also a public MCP server. Point Claude, Cursor, ChatGPT or any MCP client at https://buildersprompt.com/mcp (Streamable HTTP, JSON-RPC 2.0, no key) and you get three read tools: search_prompts, get_prompt and list_stages.

Freshness

This export is regenerated from the live database. Each prompt's updated_at is the last edit on the site. If you need a specific prompt's current text, its url is the source of truth.
