What create_module does on Plane
AI agents use create_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 create_module is rated Medium
The tool creates a new module within the Plane project management platform. This is a reversible write operation (modules can be deleted or modified). While the description is empty, the name and context of sibling Write tools, combined with the server's documented CRUD support, strongly indicate this is a Write category tool.
From the tool's definition Tool name 'create_module' indicates creation of a new module entity. Sibling tools include 'create_cycle', 'create_project', 'create_work_item' which are clearly Write operations. Server supports 'full CRUD operations' confirming write capabilities.
Attacks that exploit this kind of access
The rule that runs create_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 create_module, this is the rule to start with:
create_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 create_module call is checked against it from then on.
Questions about create_module
create_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 create_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.
create_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 create_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 create_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.
create_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.
