REGISTER AN MCP SERVER USING ERC-8004

Summary from the TLDR Crypto newsletter

The Ethereum Foundation released a technical tutorial for registering Model Context Protocol (MCP) servers onchain using ERC-8004 to address the trust gap in LLM-to-external-tool communication standards. ERC-8004 establishes three on-chain registries — Identity, Reputation, and Validation — enabling decentralized discovery and reputation-building for AI agents and MCP tools, with implementation via Agent0 SDK and IPFS.
