AI agents call retrieve_cycle 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 queries and returns cycle information by identifier. It performs no modifications, deletions, code execution, or financial transactions. The action is a straightforward read operation consistent with typical project management API retrieval endpoints.
From the tool's definition Tool name 'retrieve_cycle' and description 'Retrieve a cycle by ID' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Retrieve a cycle 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_cycle: 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_cycle 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_cycle 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_cycle. 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_cycle 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.
