WHAT IT DOES

What publish_da_data does on JS-Peer x DeFi MCP Server

AI agents use publish_da_data to create or update resources in JS-Peer x DeFi MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your JS-Peer x DeFi MCP Server environment.

WHY IT NEEDS A POLICY

Why publish_da_data needs a policy

This tool writes/publishes data to a decentralized availability (DA) network, which is a create/write operation. Once published to a DA network data is typically immutable and persistent, but the act itself is a write rather than a deletion.
