Get a list of all modules in the system
AI agents call get_module_list to retrieve information from Frappe MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries module metadata without any side effects. It is a standard Read operation similar to list/get functions. The low severity reflects minimal blast radius: an AI misuse would only surface existing system structure information already accessible to authenticated users.
From the tool's definition Tool description states 'Get a list of all modules in the system' — a retrieval operation with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Get a list of all modules in the system. It is categorised as a Read tool in the Frappe MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Frappe MCP Server MCP server in PolicyLayer and add a rule for get_module_list: 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 Frappe MCP Server. Nothing to install.
get_module_list 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 get_module_list 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 get_module_list. 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.
get_module_list is provided by the Frappe MCP Server MCP server (kiran-harbak/frappe_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
