The Builder's Prompt Library — questions

Answers built from our own checks of this server.

What can The Builder's Prompt Library do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_prompt, list_stages, search_prompts. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is The Builder's Prompt Library working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 973 ms. The bar chart above shows every period we have measured.

How do I connect The Builder's Prompt Library?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does The Builder's Prompt Library need an API key?

No. The Builder's Prompt Library completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is The Builder's Prompt Library?

It answers our handshake in 973 ms on average, which is faster than 5% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is The Builder's Prompt Library open source?

We cannot say either way: 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
