Layer C — Reference Grade

This is the reference implementation of the HiveAttest claim family. Wire format is normative. Production-grade (Layer B) is a future hardened deployment.


Reference implementation of USPTO Provisional 64/055,601 — HiveAttest claims C8/C12/C13/C15-C20.

Inventor: Stephen A. Rotzin


What this is

hive-mcp-attest is a Model Context Protocol (MCP) server that exposes the complete HiveAttest perimeter as 19 tools, proxying to the live hivemorph backend.

  • Protocol: MCP 2024-11-05 over Streamable-HTTP / JSON-RPC 2.0

  • Transport: POST /mcp

  • Discovery: GET /.well-known/mcp.json

  • Health: GET /health

  • Backend: https://hivemorph.onrender.com

  • Crypto: Ed25519, RFC 8785 JCS, SHA-256 — real signatures, no mocks

  • Brand gold: #FFB800

Cryptographic guarantees

All attestation primitives use:

  • Ed25519 — signing key generated at backend startup (or loaded from HIVE_ATTEST_PRIVATE_KEY_B64URL)

  • RFC 8785 JCS — deterministic canonicalization for all signing operations

  • SHA-256 — payload hashing, Merkle tree nodes

  • No mocked signatures — every signature is a real 64-byte Ed25519 output
