Classroom Browser MCP

A local, read-only MCP server for Google Classroom accounts that cannot grant OAuth access to the official Classroom API. It automates the same Classroom web pages you can already open and stores the browser session only in a dedicated local profile.

This is specifically for users who cannot use Google Cloud Platform (for any reason) or use their google account to sign in to unauthorised services (specifically students under DETNSW).

What it exposes

• classroom_auth_status

• classroom_find_assessment - searches Classwork and Stream posts, expands matching items, and reads attached PDFs/Google Docs

• classroom_search_activity - searches posts and Classwork, expands comments, and distinguishes direct teacher replies from related teacher-posted resources

• classroom_list_courses

• classroom_list_classwork

• classroom_get_classwork

• classroom_search_classwork

There are deliberately no submission, comment, upload, or deletion tools.

Setup

npm install
npm run login

An Edge window opens. Sign in with the school account, verify Classroom loads, and close the window. Then build the server:

npm run build
npm run verify
npm run verify -- "Assessment Task 4 Advanced"

Add it to an MCP client using this command (replace the path if needed):

{
  "mcpServers": {
    "google-classroom": {
      "command": "node",
      "args": ["D:\\classroom-mcp\\dist\\server.js"]
    }
  }
}

Configuration

Environment variables are optional:

Limits and privacy

This is UI automation, not an undocumented Google API. It can break when Classroom changes its page structure, and your school's policies still apply. The browser profile contains session cookies, so keep it private. Credentials are entered directly into Google's page and are never read or stored by this project.

MCP calls are always headless. Only npm run login opens a visible window for the one-time Google sign-in.

Only use it with an account and coursework you are authorized to access. If the school explicitly forbids browser automation, do not use it without permission.
