Prismism — questions

Answers built from our own checks of this server.

Is Prismism 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 138 ms. The bar chart above shows every period we have measured.
The registry lists Prismism 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 Prismism?
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 Prismism need an API key?
No. Prismism 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 Prismism?
The npm package @prismism/mcp-server was installed 62 times in the last week. Week over week that is +32%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Prismism open source?
Yes — it is published under the MIT licence, written in TypeScript and 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.
