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.
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.
| Tool | What it does |
|---|
passport_lookup_hktn | Lookup an HKTN registry record (tier, sovereign lineage, zone membership). |
passport_prove_well_formed | Get a smsh.prov envelope proving the passport is well-formed (verifiable offline). |
passport_prove_zone_membership | Prove an HKTN's membership (or non-membership) in a named zone (e.g. zone:hive-schengen). |
passport_get_manifest | Fetch the full service manifest: layer status, registered sovereigns, zone catalog. |
passport_get_pubkey | Get the Ed25519 pubkey for offline proof verification. |
passport_get_doctrine | Inline markdown summary of the Hive Civilization clearance doctrine. |

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.
