Get the source code of a specific function by name.
AI agents call script_get_function to retrieve information from Gworkspace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns existing function source code from Apps Script without creating, modifying, or deleting any data. It has no side effects and poses minimal security risk—the worst outcome would be unauthorized visibility into script logic, which is a read-only concern.
From the tool's definition The tool 'script_get_function' retrieves source code of a specific function by name. The verb 'get' and the explicit action of retrieving (not modifying) code without side effects clearly indicates a read operation.
Attacks that exploit this kind of access
Get the source code of a specific function by name. It is categorised as a Read tool in the Gworkspace MCP Server, which means it retrieves data without modifying state.
Register the Gworkspace MCP server in PolicyLayer and add a rule for script_get_function: 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 Gworkspace. Nothing to install.
script_get_function 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 script_get_function 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 script_get_function. 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.
script_get_function is provided by the Gworkspace MCP server (leoonic/gworkspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
