Plugs Claude into the ERC-8004 agent registry protocol running across 16 blockchain networks. You get tools to search for registered agents, register new ones, and pull reputation data straight from on-chain sources. Reach for this when you're building multi-agent systems that need verifiable identity and reputation tracking, or when you want Claude to discover and interact with agents that have established on-chain credentials. The streamable HTTP transport means you can query agent metadata, check trust scores, and validate registrations without managing blockchain infrastructure yourself. Useful for anyone working with autonomous agents where provenance and reputation actually matter.
