Tools

5 tools listed at last check
  • 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.
  • 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 -
  • 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.
  • 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.
  • 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.
