AI agents call retrieve_module to retrieve information from Plane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data (a module) by identifier without creating, modifying, deleting, or executing any operations. It is a straightforward read-only action with no side effects, placing it firmly in the Read category with low severity since unauthorized access to module metadata poses minimal risk compared to destructive or financial operations.
From the tool's definition Tool name is 'retrieve_module' and description states 'Retrieve a module by ID' — both indicate a query/fetch operation with no modifications.
Attacks that exploit this kind of access
Retrieve a module by ID. It is categorised as a Read tool in the Plane MCP Server, which means it retrieves data without modifying state.
Register the Plane MCP server in PolicyLayer and add a rule for retrieve_module: 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 Plane. Nothing to install.
retrieve_module 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 retrieve_module 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 retrieve_module. 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.
retrieve_module is provided by the Plane MCP server (@makeplane/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
