Google Apps Script MCP server

Google Apps Script MCP

English | Русский

A1 Google Apps Script MCP lets an AI app write and operate Google Apps Script in plain language. Create a script project, read and edit its code, snapshot versions, manage deployments, run functions and read the execution history.

It uses the Google Apps Script API with your Google account. It distinguishes the editable HEAD code from immutable versions and makes the limits of the Apps Script API explicit instead of implying that every scripting task is possible.

• 19 tools. Create standalone and bound projects, read and update code files, snapshot immutable versions, manage deployments, run functions, and inspect execution history and metrics.
• Connects from the conversation. Say "connect Google Apps Script": the server walks you through the OAuth client, catches Google's redirect on 127.0.0.1 with PKCE and keeps the tokens itself — no config files, no restart.
• Versions are immutable. A version snapshots HEAD and can never be edited or deleted; deployments point at versions, so you ship and roll back without changing a URL.
• The manifest always survives. Merge mode keeps the appsscript manifest and every file you did not mention; replace mode refuses a file set without the manifest before any network traffic.
• Keep your scriptId. The API cannot list projects and cannot delete them — the scriptId returned by create_project is the only handle.
• Minimal Google scopes. Each operation names its own scope (script.projects, script.deployments, script.processes, script.metrics); request only what your tasks need.

Start with a read-only question:

Show me the files in my report script and which functions failed this week.

You: Show the code and the recent runs of my report script.

Assistant: Shows every file with its source and the execution history — which functions ran, when, and which failed. Nothing changes.

You: Add a formatDate helper to the Utils file and keep everything else as is.

Assistant: Shows the proposed source and confirms that merge mode leaves the other files untouched, then asks for confirmation before writing.

You: Confirm.

Assistant: Writes the file to HEAD. It does not create a version, redeploy or run anything unless you ask separately.

Quick start

You need Node.js 20+ and a Google account. Credentials are not required at install time — the server connects from the conversation.

1. Add the server to your AI app.
2. Say "connect Google Apps Script": the assistant walks you through creating the OAuth client and approving access without editing config files.
3. Ask the read-only question above.
