HiveEcho is an MCP server for point-in-time state queries, Merkle proof generation, and contract state anchoring. It provides immutable event logging and an audit trail for agent transactions, exposing MCP tools over HTTP endpoints and focusing on temporal state access and cryptographic proofs.

🛠️ Key Features

Point-in-time state queries for any entity
Merkle proof generation for historical state verification
Contract state anchoring to enhance immutability and auditability
Exposes MCP tools via POST /mcp/tools and POST /mcp/execute

🚀 Use Cases

Retrieve historical entity state at a given timestamp
Generate verifiable proofs that a state existed at a specific time
Anchor contract state for tamper-evident audit trails

⚡ Developer Benefits

Clear MCP tooling: hiveecho_query_state and hiveecho_generate_proof
Deterministic, cryptographic state proofs for audits
Lightweight server designed for immutability-focused workflows

⚠️ Limitations

Described features rely on readmeExcerpt and may not reflect all capabilities
Requires proper timestamping to ensure accurate historical queries

MCP Tools

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

Tool

Description

hiveecho_query_state

Query the historical state of any entity at a specific point in time, or retrieve its current state

hiveecho_generate_proof

Generate a Merkle proof that a specific state existed at a given timestamp. Returns cryptographic proof path for third-party verification

hiveecho_anchor_contract

Capture a cryptographic snapshot of all parties' state at the moment of contract signing for immutable provenance

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.
