WHAT IT DOES

What verify-contract does on RSK MCP Server - Rootstock Blockchain Tools

AI agents invoke verify-contract to trigger actions in RSK MCP Server - Rootstock Blockchain Tools. 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 verify-contract needs a policy

Contract verification submits source code and metadata to an external blockchain explorer/service for validation against deployed bytecode. This triggers an external operation (blockchain verification service interaction) rather than simply reading data or writing local data.
