Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Package points at a different repository cg3-llc/prior_mcp
пакет @cg3/prior-mcp ссылается на cg3inc/prior_mcp

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Prior — questions

Answers built from our own checks of this server.

Is Prior working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 32 ms. The bar chart above shows every period we have measured.
The registry lists Prior 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 Prior?
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 Prior need an API key?
No. Prior completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How many people use Prior?
The npm package @cg3/prior-mcp was installed 46 times in the last week. Week over week that is -40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Prior open source?
No, and the distinction matters: its licence is declared as FSL-1.1-ALv2. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
