WHAT IT DOES

What create_libp2p_node does on JS-Peer x DeFi MCP Server

AI agents invoke create_libp2p_node to trigger actions in JS-Peer x DeFi MCP Server. 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_libp2p_node needs a policy

Creating and initializing a libp2p node is an Execute-category action — it starts a new networked process/service with configurable parameters. This is not a simple data write; it spawns an active peer-to-peer network node that can interact with external systems. Misuse could expose the host to unwanted network connections or resource consumption, warranting medium severity.

create_libp2p_node Rate-limited

create_libp2p_node 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.
