AI agents use GOOGLEDRIVE_FILES_MODIFY_LABELS to create or modify resources in Google Drive. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call GOOGLEDRIVE_FILES_MODIFY_LABELS repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Google Drive.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Modifies the set of labels applied to a file. returns a list of the labels that were added or modified. use when you need to programmatically change labels on a google drive file, such as adding, updating, or removing them.. It is categorised as a Write tool in the Google Drive MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Drive MCP server in PolicyLayer and add a rule for GOOGLEDRIVE_FILES_MODIFY_LABELS: 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 Google Drive. Nothing to install.
GOOGLEDRIVE_FILES_MODIFY_LABELS 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 GOOGLEDRIVE_FILES_MODIFY_LABELS 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 GOOGLEDRIVE_FILES_MODIFY_LABELS. 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.
GOOGLEDRIVE_FILES_MODIFY_LABELS is provided by the Google Drive MCP server (@modelcontextprotocol/server-gdrive). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
