AI agents call list_cycle_work_items 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.
The tool retrieves or queries work items associated with a cycle, consistent with Read category operations. The empty description lowers confidence slightly, but the naming convention and context from sibling tools (which include Write operations like 'create_cycle', 'create_label') strongly suggest this is a non-destructive data retrieval operation. No side effects or data modification capability is implied.
From the tool's definition Tool name 'list_cycle_work_items' indicates a retrieval/query operation that lists work items within a cycle. The 'list' prefix is a strong indicator of a Read operation that queries data without modifying it.
Attacks that exploit this kind of access
list_cycle_work_items. 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 list_cycle_work_items: 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.
list_cycle_work_items 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 list_cycle_work_items 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 list_cycle_work_items. 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.
list_cycle_work_items 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.
