update_project_estimate · Plane MCP: Risk & Policy

WHAT IT DOES

What update_project_estimate does on Plane

AI agents use update_project_estimate 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 IT NEEDS A POLICY

Why update_project_estimate needs a policy

This tool creates or modifies project estimate data reversibly, which aligns with the Write category. The empty description reduces confidence slightly, but the naming convention and context within a project management server (Plane) that handles work items, cycles, and modules strongly suggests this performs estimation updates.

From the tool's definition Tool name 'update_project_estimate' indicates modification of project estimation data. The prefix 'update_' clearly signals a write operation that alters existing data.

update_project_estimate Rate-limited

update_project_estimate 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.
