create_work_log · Plane MCP: Risk & Policy

WHAT IT DOES

What create_work_log does on Plane

AI agents use create_work_log 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 create_work_log needs a policy

Work log creation modifies project tracking data by adding a new log entry. This is a reversible write operation that creates data without deleting, destroying, or executing arbitrary code. The severity is medium because misuse could clutter project records or log false time entries, but the blast radius is limited to project management data, not code execution or data destruction.

From the tool's definition Tool name is 'create_work_log' indicating creation of a new work log entry; sibling tools include create_cycle, create_initiative, create_label, create_module which are all Write operations; description is empty, limiting direct evidence

Verdict

create_work_log Rate-limited

create_work_log 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.
