Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: GreenCore Solutions Corp. — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.4.1
Auth schemes: bearerJwt entraOAuth2
Extensions: https://gsc-em.com/a2a/ext/scope-of-authority/v1
GSC scope of authority: read, resolve and discovery calls are autonomous; every transactional commit (order, RFQ acceptance, terms) is human-signed at the GSC Trading Desk / Navigator HITL boundary.
https://gsc-em.com/a2a/ext/marketplace/v1
The fifth GSC surface — selection. Eleven read tools over MCP; x402 capability on the single paid HTTP endpoint /api (terms in its 402 payload only).
https://gsc-em.com/a2a/ext/enforcement-posture/v1
These endpoints are open by design. When the buy side's credential standard reaches GA — expected Q4 2026-Q1 2027 — transactional methods migrate to OAuth 2.1 challenge per the MCP 2025-11-25 specification. Read access stays open. That is not pending w

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
