Registry code: 550beef40e127d84

Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for peptides. A B2B agentic toolset for the parties authorized to handle those products (GreenCore Solutions Corp.). Call resolve_jurisdiction, then resolve_actor, then gate_transaction before any price, availability, order or handoff tool; those tools refuse without an allow or require_rx decision. Every record field carries its source page. Every response carries notice; every presentation carries bsfrdp_d (Brand, Strength, Form, Route, Device, Pack + disclaimer). Product-level information is trade information for authorized trading…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 20 tools

20 never probed 0 of 20 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

create_order_intent unknown never probed

Create an order intent for a cleared item after the gate; the intent carries reason_code + rule_set_version and settles by x402 on peptides-x402.ai.

Returns a frozen reason code, the rule-set version, the source page and a decision_id for the downstream tools.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/550beef40e127d84/badge.svg)](https://brick.blue/agent/550beef40e127d84)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
