Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

build
build_prompt
Compose a ready-to-use prompt from explicit Role, Task, Context, and Format parts. Use when the user already knows the pieces and wants them woven into one clean prompt.
improve
improve_prompt
Rewrite a rough prompt into a sharper, ready-to-use prompt structured as Role, Task, Context, Format (RTCF). Returns the improved prompt plus its four parts. Use this before answering when the user's request is vague, or when the user asks to improve a prompt.

Rtcf — questions

Answers built from our own checks of this server.

What can Rtcf do?
It exposes 2 tools, read directly from the server on our last check. Among them: build_prompt, improve_prompt. 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 Rtcf working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 216 ms. The bar chart above shows every period we have measured.
The registry lists Rtcf as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Rtcf?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Rtcf need an API key?
No. Rtcf completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
Is Rtcf open source?
Yes — 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
