create_swarm · Tenzro Ledger MCP: Risk & Policy

WHAT IT DOES

What create_swarm does on Tenzro Ledger MCP

AI agents invoke create_swarm to trigger actions in Tenzro Ledger MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why create_swarm needs a policy

This tool instantiates and orchestrates multiple AI agents, which constitutes triggering external operations. Given the server context (wallet, identity, payments, inference, staking, bridges), spawning a swarm of agents could have wide-ranging and hard-to-predict effects across financial and infrastructure systems.

create_swarm Rate-limited

create_swarm stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
