A2A Agent Card · MUJ428 LLC

MUJ428 Trust Reflex

MUJ428 — VERIFY BEFORE ACT. Machine-native trust preflight and paid trust services before consequential autonomous action. Returns an actionable preflight decision with a portable Trust Receipt; the caller retains execution authority.

⚠ Agent card, not A2A. MUJ428 LLC serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
