AI agents use resolveComment 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.
This tool modifies comment status from unresolved to resolved, which is a reversible write operation. It changes metadata on existing comments without deleting or creating new data. The severity is low because: (1) the operation is reversible (comments can be re-opened), (2) it affects only comment metadata, not document content, and (3) the tool has acknowledged limitations that reduce its real-world impact.
From the tool's definition Tool description states it 'Marks a comment as resolved', which is a state change operation on existing data (comments).
Attacks that exploit this kind of access
Marks a comment as resolved. IMPORTANT LIMITATION: The Google Drive API does not fully support resolving comments on Google Docs files. While this tool will attempt to set the resolved status, it typically does NOT persist in the Google Docs UI. This is a known Google API limitation, not a bug in this tool. To reliably resolve comments, users should resolve them manually in the Google Docs interface. This tool is provided for completeness but has limited practical utility for Docs files. It is categorised as a Write tool in the Google Workspace MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Workspace MCP Server MCP server in PolicyLayer and add a rule for resolveComment: 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 Workspace MCP Server. Nothing to install.
resolveComment 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 resolveComment 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 resolveComment. 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.
resolveComment is provided by the Google Workspace MCP Server MCP server (pm990320/google-workspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
