Source code Website Documentation

What can you do with HiveEcho?

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

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http hiveecho 'https://hiveecho.onrender.com/mcp'
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "hiveecho": {
            "type": "http",
            "url": "https://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

Hive Civilization

Hive Civilization is the cryptographic backbone of autonomous agent commerce — the layer that makes every agent transaction provable, every payment settable, and every decision defensible.

This repository is part of the PROVABLE · SETTABLE · DEFENSIBLE pillar.

Frequently asked questions

What is HiveEcho?

Immutable event logging and audit trail for agent transactions

How do I install HiveEcho?

It runs as a remote server. In Claude Code: claude mcp add --transport http hiveecho 'https://hiveecho.onrender.com/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does HiveEcho need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is HiveEcho open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains HiveEcho?

It is published by srotzin. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
