What insertLocalImage does on Google Workspace MCP Server

AI agents use insertLocalImage to create or update resources in Google Workspace MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Workspace MCP Server environment.

Medium Risk

Why insertLocalImage needs a policy

This tool creates new data (uploaded image file on Drive) and modifies existing data (inserts content into a document), both reversible operations characteristic of Write category. The severity is medium because misuse could fill storage, modify shared documents without authorization, or insert inappropriate content, but effects are undoable (file deletion, image removal).

From the tool's definition Tool description states it 'Uploads a local image file to Google Drive and inserts it into a Google Document'—core Write operations: upload (creates new Drive resource) and insert (modifies document).

How to control insertLocalImage

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Workspace MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for insertLocalImage:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "insertLocalImage": {
      "limits": [
        {
          "counter": "insertlocalimage_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

insertLocalImage stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Google Workspace MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
