Nothing serious here today

Today is the operative word: we check Postall every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Postall — questions

Answers built from our own checks of this server.

Why is there no uptime for Postall?

Postall 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 postall-mcp-server was installed 22 times last week.

How do I connect Postall?

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 postall-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Postall?

The npm package postall-mcp-server was installed 22 times in the last week. Week over week that is -27%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Postall open source?

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