Tools as reported by the server

• intentfence_authorize_action
  Authorize an exact agent action against an explicit allowlist, spend ceiling, retention ceiling, and optional action-bound approval. Returns a five-minute ES256 receipt and never executes the downstream action. Callers must verify the receipt and fail closed if the action changes.
• intentfence_agent_risk_scan
  Free metadata-only scan of caller-supplied MCP tool definitions for missing schemas, unsafe annotations, approval binding, and cost boundaries. Does not execute tools or certify security.
• intentfence_checkout
  Free machine checkout builder. Select a paid IntentFence outcome and receive the exact endpoint, validated request, USDC cap, shell-safe Agentic Wallet argv, MCP tool call, and opt-in local auto-payment budget. It never signs or initiates payment.
• intentfence_preflight
  Free declared-input preview with no signed receipt, authorization proof, or enforcement guarantee. Returns safe_to_proceed, needs_review, or denied.
• intentfence_policy_pack
  Paid self-service integration pack (1 USDC on Base). Generates a runtime-specific TypeScript guard, signed action and policy receipt, negative test vectors, and a fail-closed deployment checklist for Cloudflare Agents, Coinbase AgentKit, or an MCP gateway. No meeting or account is required.

  Paid production preflight ($0.005 USDC on Base). Settles through x402 and returns a signed ES256 audit receipt plus settlement metadata.

• intentfence_x402_readiness
  Paid live endpoint check ($0.002 USDC on Base). Makes one bounded credential-free request to a public HTTPS target, blocks private networks and redirects, never pays the target, validates the returned x402 challenge, and returns a signed five-minute receipt.
• intentfence_wallet_risk
  Paid AML/KYT wallet screening ($0.002 USDC on Base) before sending funds or approving a transaction. Checks live Base activity plus GoPlus sanctions, phishing, mixer, money-laundering, dark-web, blacklist, and related counterparty-risk flags, then returns a five-minute ES256 receipt. A low-risk resu
• intentfence_us_cpi
  Paid official U.S. CPI and core CPI data ($0.001 USDC on Base), retrieved from the Bureau of Labor Statistics with a six-hour edge cache and returned with an ES256 provenance receipt. Optionally request a YYYY-MM period.
