APEX PSI — questions

Answers built from our own checks of this server.

Why is there no uptime for APEX PSI?
APEX PSI runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package apex-psi-mcp was installed 26 times last week.
How do I connect APEX PSI?
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 runs locally, so the command pulls apex-psi-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use APEX PSI?
The npm package apex-psi-mcp was installed 26 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is APEX PSI open source?
We cannot say that it is: written in JavaScript and 1 stars on GitHub, but no licence is declared, and without one the code is not open source by default.
