PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Docs, sheets & office work
  • You need to fill in: GOOGLE_CLIENT_SECRET, MICROSOFT_CLIENT_SECRET

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_OAUTH_CREDENTIALS, MICROSOFT_CLIENT_ID, MICROSOFT_CLIENT_SECRET, TIMEZONE, WEEK_START, TENANT_ID, LOCK_TTL_SECS, OAUTH_REDIRECT_PORT, HTTP_PORT, HTTP_HOST, ALLOWED_ORIGINS, TEMPORAL_CORTEX_TELEMETRY, REDIS_URLS

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?
