Hive Passport MCP

by srotzin

Hive Passport MCP

The atomic A2A clearance graph. HKTN registry lookup, ZK-provable well-formedness, zone membership proofs, sovereign manifest — all served as a Model Context Protocol tool surface.

MCP Hive License

What this is

A thin MCP server that fronts the live hive-passport.onrender.com clearance backend. As of May 3, 2026 (Hour 7), every Hive Knowledge Token (HKTN) ships with an active passport at mint — atomically, in a single Postgres transaction. This MCP server lets any agent client look up HKTNs, request signed proofs, and integrate the Hivery's A2A clearance into its own flows.

State of the colony (May 3, 2026)

  • 28 active HKTNs with 1:1 active passport invariant

  • 6 sovereigns issuing attestations: hive-treasury, hivemorph-corp, hivecompute, hive-passport, spectralzk, hive-schengen-charter

  • 17 charter HKTNs in zone:hive-schengen (auto-provisioned at mint)

  • ~104K reputation_credits in the Reckoning ledger

  • Layers 1-4 live, Layer 5 (Duty-free Terminal) reserved at 501

A2A flow

Mint → Reckoning → Passport → Stamp → Tier → Vouch → Zone → A2A Consume

The first three stages run in a single transaction (Hour 7 atomic-mint guarantee, May 3 2026). No HKTN exists without an active passport.
