What update_module does on Plane
AI agents use update_module to create or update resources in Plane, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Plane environment.
Why update_module is rated Medium
Based on naming convention and context, 'update_module' most likely creates or modifies module data reversibly in the Plane project management platform. Without an explicit description, confidence is reduced slightly, but the pattern of CRUD operations across the server and the 'update_' prefix strongly indicate a Write operation rather than Read, Execute, Destructive, or Financial.
From the tool's definition Tool named 'update_module' with no description provided. Sibling tools on this server include 'create_module' (categorized as Write) and 'delete_work_item' (categorized as Destructive), suggesting this is part of a project management CRUD system.
Attacks that exploit this kind of access
The rule that runs update_module safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_module, this is the rule to start with:
update_module stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Plane, apply this rule, and every update_module call is checked against it from then on.
Questions about update_module
update_module is a write tool on the Plane MCP server. It is categorised as a Write tool in the Plane MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Plane MCP server in PolicyLayer and add a rule for update_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.
update_module is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_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 update_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.
update_module is provided by the Plane MCP server (cmet7/plane-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
