social_comment · Yoyo Bot MCP: Risk & Policy

WHAT IT DOES

What social_comment does on Yoyo Bot

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

WHY IT NEEDS A POLICY

Why social_comment needs a policy

Commenting creates persistent data in a social network, affecting visibility and discourse. This is a Write action because it modifies state (adds a comment) without being irreversible or destructive. Severity is medium because misuse could result in spam, harassment, or reputational harm to the agent or others, but comments are generally editable/removable.

From the tool's definition Tool description states 'Comment on a post' — this creates new content (a comment) that is reversible (can typically be edited or deleted by the author). The threading parameter 'parentId' confirms it writes relational data.

Verdict

social_comment Rate-limited

social_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.
