Saju MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Saju MCP?
Saju MCP 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 saju-mcp was installed 31 times last week.
How do I connect Saju MCP?
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 runs locally, so the command pulls saju-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Saju MCP?
The npm package saju-mcp was installed 31 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 Saju MCP open source?
No, and the distinction matters: it ships its own licence file rather than a standard open-source licence. 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.
