editTableCell

THE RISK

Medium Risk

Why editTableCell needs a policy

This tool modifies existing cell content and styling in a table (likely within a Google Doc or Sheet), which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), or move money (Financial). The modification is bounded to a single cell's content and formatting, making it a Write-category risk.

From the tool's definition Tool description explicitly states it 'Edits the content and/or basic style of a specific table cell', using the verb 'Edits' which indicates modification of data.

POLICY

How to control editTableCell

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 editTableCell:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "editTableCell": {
      "limits": [
        {
          "counter": "edittablecell_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

editTableCell 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.

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