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:
| 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 |
Endpoints
POST /mcp/tools— List available MCP toolsPOST /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
