**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 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
