GateCheck by LarryBuildsAI
Paid-tool readiness scorecard.
GateCheck gives paid x402 and MCP sellers a buyer-readable preflight before launch. It shows whether the public surfaces are discoverable, the tool inventory is inspectable, price/resource metadata is visible, and the claim boundary is explicit before agents or buyers route paid calls.
7 checksDiscovery, tools, pricing, 402 behavior, directory visibility, claim boundary, and next step.
6 toolsPublic MCP introspection exposes the GateCheck tool inventory before protected calls.
$1-$49Readiness checks and launch-pack tiers give sellers small proof steps.
0 secretsPublic metadata checks require no private keys, cookies, wallets, or customer data.
| Area | Status | Evidence |
|---|---|---|
| Discovery | Pass | Product-scoped homepage, llms.txt, agents.txt, product card, skill card, sitemap, and MCP server card are available for buyer and crawler inspection. |
| Tools | Pass | The product-scoped MCP endpoint supports public initialize and tools/list introspection with six GateCheck tools. |
| Pricing | Pass | Owned docs expose quick readiness, report, launch-pack, paid-path probe, scan, and receipt price bands before any buyer signs or spends. |
| 402 | Pass | GateCheck can inspect unpaid 402 challenge metadata for paid endpoints without submitting payment signatures or moving funds. |
| Directories | Partial | Registry-linked and directory pages are trackable; xpay central agents.txt propagation is not claimed until public evidence appears. |
| Boundary | Pass | Reports are limited to observed metadata, unpaid 402 behavior, request summaries, hashes, and explicit non-claims. |
| Next Step | Ready | Sellers can run a readiness check, share the sample report, then package a launch only after evidence is clean. |
Claim boundary:
GateCheck reports and receipts prove observed public metadata, unpaid 402 behavior, request summaries, hashes, and returned artifacts only. They do not prove marketplace endorsement, settlement, security certification, custody, KYC/AML coverage, buyer adoption, or downstream execution.
