List all functions in a script project with their file, signature, and line numbers.
AI agents call script_list_functions 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 queries and returns metadata about functions (file, signature, line numbers) in an Apps Script project. It performs no side effects, does not execute code, does not modify data, and merely provides introspection into existing script structure. This is a straightforward Read operation with minimal blast radius.
From the tool's definition Tool name is 'script_list_functions' and description states it 'List all functions in a script project' — a retrieval operation with no modification or execution of code.
Attacks that exploit this kind of access
List all functions in a script project with their file, signature, and line numbers. 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_list_functions: 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_list_functions 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_list_functions 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_list_functions. 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_list_functions 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.
