Execute one or more batch update requests on a spreadsheet. Supports any Sheets API batchUpdate request type (addSheet, deleteSheet, updateCells, mergeCells, etc.)
AI agents use google_sheets_batch_update to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
An AI agent can call google_sheets_batch_update faster than any human can review — one bad instruction and it creates or modifies resources in Sage MCP by the hundred, each call as confident as the last.

Documented attack patterns abuse exactly the kind of access google_sheets_batch_update gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for google_sheets_batch_update:
{
"version": "1",
"default": "deny",
"tools": {
"google_sheets_batch_update": {
"limits": [
{
"counter": "google_sheets_batch_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}google_sheets_batch_update 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.

Execute one or more batch update requests on a spreadsheet. Supports any Sheets API batchUpdate request type (addSheet, deleteSheet, updateCells, mergeCells, etc.). It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for google_sheets_batch_update: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Sage MCP. Nothing to install.
google_sheets_batch_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the google_sheets_batch_update rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for google_sheets_batch_update. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
google_sheets_batch_update is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
