## Tools
- boundary_guard_check (Boundary Guard Check) - Create a deterministic, read-only pre-action receipt from request, policy, and optional result evidence. Use before an agent posts, spends, lists, or writes so the decision can be audited; no external action is executed. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
- scan_x402_resource (x402 Resource Scan) - Read-only scan of a public API/provider URL for x402, OpenAPI, pricing, and agent-discovery metadata. Pass url, and optionally marketplace_url plus expected_resources, to get a readiness score, issues, and fixes; no private endpoints are called. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
- probe_x402_paid_path (x402 Paid-Path Health Probe) - Probe a public x402 paid endpoint without signing or paying, then parse the HTTP 402 challenge. Pass target plus optional expected network/asset/price to verify payment metadata and receive a deterministic health receipt. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
- check_agent_tool_readiness (GateCheck Readiness) - GateCheck readiness: check whether an x402/agent-facing tool is ready for agent routing, marketplace listing, and paid-path monitoring, including public agent discovery surfaces (/llms.txt, /agents.txt, /.well-known/mcp.json, /mcp). Pass target plus optional tier, marketplace_url, expected_resources, and paid_path; deep/report tiers add unpaid 402 probing when paid_path is supplied. Tiers: quick $1, deep $5, report $10. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
- generate_x402_launch_pack (x402 Launch Pack Generator) - Generate marketplace-safe launch assets for an x402/MCP seller: listing copy, buyer FAQ, checklist, approval packet, and claim boundaries. Pass target plus optional product_name, audience, primary_use_case, marketplace_url, and paid_path; service/premium tiers include readiness evidence. Tiers: single $9, service $29, premium $49. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
- generate_trust_receipt (Generate Trust Receipt) - Generate a deterministic trust receipt from sanitized request/policy/result/payment summaries. Do not submit raw auth headers, cookies, API keys, private keys, payment signatures, payment response headers, customer prompts, customer documents, or payer-identifying evidence. Endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp
