Check system dependencies and environment
AI agents call dependency_check to retrieve information from Google Apps Script MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool inspects the current system state (dependencies and environment variables) to gather information. It performs no modifications, deletions, or external operations. It is purely informational, similar to a 'list' or 'get' operation. The low severity reflects that misuse would only expose information about the host environment, which is typically non-sensitive in the context of development tooling.
From the tool's definition Tool name 'dependency_check' and description 'Check system dependencies and environment' indicate inspection/querying of existing state. The verb 'check' is diagnostic with no modification capabilities.
Attacks that exploit this kind of access
Check system dependencies and environment. It is categorised as a Read tool in the Google Apps Script MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Apps Script MCP Server MCP server in PolicyLayer and add a rule for dependency_check: 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 Apps Script MCP Server. Nothing to install.
dependency_check is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the dependency_check 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 dependency_check. 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.
dependency_check is provided by the Google Apps Script MCP Server MCP server (utakata/google-apps-script-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
