## Tools (as reported by the server, not verified)

- `rescue\_agent\_before\_consequence`: MUJ428 Agent Rescue Beacon. Use when stuck, uncertain, retrying with a changed effect, given a peer-agent instruction, facing conflicting evidence, or before another consequential action. Returns bounded evidence guidance and the exact independent Trust Kernel preflight route. It never grants execut
- `trust\_action`: Invoke the canonical MUJ428 Trust Reflex before a consequential action. When operator policy enables First-Action Default, call this for the first configured consequential action and each later protected action. First 1,000 qualifying decisions per caller\_ref are free. After quota, the tool returns
- `invoke\_trust\_service`: Generic beginning-to-end MUJ428 service bridge. Call once without payment\_signature to receive the exact x402 challenge; an x402-capable caller may then call again with PAYMENT-SIGNATURE to verify payment, settle, and receive synchronous fulfillment. No payment is initiated unless the caller explici
- `get\_service\_catalog`: Return the canonical MUJ428 service catalog, launch prices, endpoints, free Trust Reflex quota, default x402 network, and multi-rail discovery endpoint.
- `get\_payment\_rails`: Discover MUJ428 payment capabilities and their truthful activation state. This is read-only and moves no funds. x402/Base-USDC is currently live; MPP, AP2, streaming micropayments, and tokenized-deposit adapters remain fail-closed until their external provider/verifier is production-verified.
- `resolve\_trust\_route`: MUJ428 Agent Router and Trust DNS resolver. Determine whether an intended action requires Trust Receipt v1.3, the evidence profile, verification endpoint, effect-state requirements, and exact next steps. This read-only routing call never authorizes execution or payment.
- `get\_trust\_heartbeat`: Poll the MUJ428 Trust Heartbeat for current policy epoch, accepted receipt version, revocation state, resolver endpoints, and recommended poll interval. Read-only; no execution or payment authority.
- `find\_trust\_capabilities`: Search the MUJ428 compatibility directory for evidence providers, receipt-aware executors, wallets, MCP/A2A integrations, and other trust capabilities. SELF\_ATTESTED\_UNVERIFIED entries are discovery leads only.
- `publish\_trust\_request`: Publish a bounded machine-readable request for a trust capability and receive current compatibility matches. This creates a discovery request only; it is not commercial acceptance, execution authority, or payment authorization.
- `observe\_trust\_compatibility`: Record that an agent encountered a MUJ428 compatibility advertisement so propagation can be measured. Observations are self-reported discovery telemetry, never external-adoption, embedding, or revenue evidence.
- `select\_payment\_rail`: Preflight a requested payment rail before Trust Reflex. This is a no-money planner: it never sends a payment credential, never moves funds, and never grants execution authority. Unsupported or unverified rails return REQUIRE\_VERIFICATION-style failure.
- `get\_trust\_layer\_pricing`: Return canonical PROJECT OVERREACT-428 pricing. Airtable Commercial Pricing Authority remains the source of truth.
- `select\_assurance\_tier`: Calculate the exact MUJ428 Transaction Assurance launch fee before payment. Does not move money.
- `get\_capabilities`: Return MUJ428 canonical machine discovery surfaces, payment-rail discovery, Trust Gravity routing, and the recommended adoption path.
