join_swarm · MonetizeAgent MCP: Risk & Policy

WHAT IT DOES

What join_swarm does on MonetizeAgent

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

WHY IT NEEDS A POLICY

Why join_swarm needs a policy

Joining a swarm is a Write operation because it creates a new membership record or updates swarm participation state. While it may have downstream effects (financial obligations if the swarm has revenue-sharing mechanisms), the tool itself only requests membership without directly transferring money or executing arbitrary external code.

From the tool's definition Tool description states 'Request to join an agent swarm' — this creates or modifies membership state in a swarm, a reversible action that writes data about the agent's participation.

Verdict

join_swarm Rate-limited

join_swarm 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.
