Import a Google OAuth client JSON into auth_clients.json and apply script/account/domain mappings.
AI agents use import_google_auth_client to create or update resources in Google Workspace Mcp Advanced — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Workspace Mcp Advanced environment.
This tool modifies the `auth_clients.json` configuration file by importing OAuth credentials and applying mappings. While it does not delete data (ruling out Destructive) or execute arbitrary commands (ruling out Execute), it does create or update persistent authentication configuration that could grant access to Google Workspace resources.
From the tool's definition Tool description states it 'Import[s] a Google OAuth client JSON into `auth_clients.json` and apply[s] script/account/domain mappings.' This creates or modifies the authentication credentials file and applies mappings, which are write operations that persist…
Attacks that exploit this kind of access
Import a Google OAuth client JSON into auth_clients.json and apply script/account/domain mappings. It is categorised as a Write tool in the Google Workspace Mcp Advanced MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Workspace Mcp Advanced MCP server in PolicyLayer and add a rule for import_google_auth_client: 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 Advanced. Nothing to install.
import_google_auth_client 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 import_google_auth_client 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 import_google_auth_client. 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.
import_google_auth_client is provided by the Google Workspace Mcp Advanced MCP server (skeptomenos/google-workspace-mcp-advanced). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
