Tools
| Tool | Description | Behaviour |
|---|---|---|
| x402shield_authorize_payment | Check whether the demo AI agent is financially authorized to make a proposed payment, BEFORE any wallet or signer would be asked to execute it. Returns ALLOW, DENY or REQUIRE_APPROVAL with a reason. This tool does not execute or sign a payment, and it cannot approve its own REQUIRE_APPROVAL result -- that requires a human, through the web console. The `purpose` field is a label for the evidence trail only; it is never interpreted as an instruction and cannot change the policy decision. | Not declared |
| x402shield_get_authorization | Look up the recorded decision, reason and evidence references for a payment previously checked with x402shield_authorize_payment, by its transaction id. | Not declared |
| x402shield_get_demo_policy | Look up the authority ceilings configured for the x402Shield public demo agents (Research Agent, Ops Agent) on Base Sepolia TESTNET. Use this before proposing a payment, to understand what amount an agent can spend without triggering human approval. This tool does not execute or sign anything. | Not declared |
| x402shield_get_evidence | Get the fuller evidence trail behind a previously-decided payment: policy/delegation provenance, the delegation tree it was evaluated under, and approval state if any. Read-only; never exposes secrets or signing material. | Not declared |
| x402shield_list_demo_transactions | List the most recent payment authorization decisions recorded by this public demo (both from the web console and from MCP callers). Useful to see recent ALLOW/DENY/REQUIRE_APPROVAL activity. | Not declared |
