WHAT IT DOES

What submit_oracle_data does on JS-Peer x DeFi MCP Server

WHY IT NEEDS A POLICY

Why submit_oracle_data needs a policy

This tool creates/modifies oracle data that other systems and smart contracts depend on for decision-making. In DeFi contexts, oracle data directly influences financial decisions (loan liquidations, trading, etc.). Submitting false or manipulated data constitutes a Write operation (data modification) rather than Destructive (not irreversible).

From the tool's definition Tool name 'submit_oracle_data' and description 'Submit price or data feed to oracle network' indicate creation or modification of data (price/data submissions) in an external oracle system.
