add_comment · Taskflow MCP: Risk & Policy

WHAT IT DOES

What add_comment does on Taskflow MCP

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

WHY IT NEEDS A POLICY

Why add_comment needs a policy

Adding a comment is a reversible write operation that appends data to an existing task record. It does not execute code, delete data, move funds, or trigger external operations with unpredictable effects. The severity is low because comments are typically non-critical metadata and easily remedied if inappropriate content is added.

From the tool's definition Tool description states 'Add a comment to a Notion task', which creates new comment data in Notion without modifying the task itself or being destructive.

Verdict

add_comment Rate-limited

add_comment 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.
