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 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
