HiveEcho

HiveEcho is a Model Context Protocol (MCP) server designed for immutable event logging, temporal state queries, and generation of cryptographic proofs. It exposes tools allowing AI agents and systems to query historical states, generate Merkle proofs for state verification, and anchor contract states for audit trails and provenance. Integrating with Node.js/Express and supporting Merkle tree proof generation and event sourcing, HiveEcho is ideal for use cases involving state integrity, third-party verification, and contract auditing—such as compliance, finance, and legal domains.
