commentCard · Wekan MCP Server MCP: Risk & Policy

WHAT IT DOES

What commentCard does on Wekan MCP Server

AI agents use commentCard to create or update resources in Wekan MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wekan MCP Server environment.

WHY IT NEEDS A POLICY

Why commentCard needs a policy

Adding a comment is a write operation that creates reversible data. It does not execute code, delete data, move money, or have destructive effects. A misclassified comment is easily corrected, making the blast radius minimal. The operation is bounded to appending comment data to a specific card, with no system-wide impact.

From the tool's definition Tool description states 'Add a comment to a card', which creates new data (a comment) on an existing card in the Wekan kanban board.

Verdict

commentCard Rate-limited

commentCard 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.
