MOST DANGEROUS TOOLS

High Risk

The most dangerous Google Sheets OAuth MCP tools

Write · Medium append_rows The tool creates new data (appends rows) in a spreadsheet owned by the user. Write · Medium create_sheet This tool creates new spreadsheets and can optionally write data (header rows) and modify sharing permissions. Write · Medium update_range This tool creates or modifies data in a spreadsheet range without permanent deletion.

3 of Google Sheets OAuth MCP's 4 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Google Sheets OAuth MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Sheets OAuth MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "append_rows": {
    "limits": [
      {
        "counter": "append_rows_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "read_range": {
    "limits": [
      {
        "counter": "read_range_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
