Summary

Gives Claude three MCP tools for cryptographic audit trails: query_state for point-in-time lookups of any entity's historical state, generate_proof for creating Merkle proofs of what existed when, and anchor_contract to snapshot multi-party state at signing time. Built on event sourcing with temporal reconstruction, so you can rewind to any timestamp and prove what the world looked like then. Reach for this when you need verifiable history for dispute resolution, compliance auditing, or any scenario where "trust me" isn't good enough. Exposes standard MCP endpoints over streamable HTTP at hiveecho.onrender.com/mcp.

HiveEcho

Temporal State Queries & Cryptographic Proofs — MCP Server

HiveEcho is a Model Context Protocol (MCP) server for point-in-time state queries, Merkle proof generation, and contract state anchoring.

MCP Tools

HiveEcho exposes the following MCP tools via POST /mcp/tools and POST /mcp/execute:

ToolDescription
hiveecho_query_stateQuery the historical state of any entity at a specific point in time, or retrieve its current state
hiveecho_generate_proofGenerate a Merkle proof that a specific state existed at a given timestamp. Returns cryptographic proof path for third-party verification
hiveecho_anchor_contractCapture a cryptographic snapshot of all parties' state at the moment of contract signing for immutable provenance

Endpoints

  • POST /mcp/tools — List available MCP tools
  • POST /mcp/execute — Execute an MCP tool

Use Cases

  • Verify what state an entity was in at any past timestamp
  • Generate cryptographic proofs for dispute resolution
  • Anchor multi-party contract state for auditing

Tech Stack

  • Node.js / Express
  • Merkle tree proof generation
  • Event sourcing with temporal reconstruction
