  "markdown": "# GateCheck by LarryBuildsAI\n\nGateCheck is a hosted remote MCP server and x402 readiness surface for paid agent-tool sellers.\n\nUse it before public submission, promotion, or paid agent routing to verify that a paid x402 or MCP tool is discoverable, inspectable, and claim-bounded.\n\n## Hosted MCP Endpoint\n\n- Remote MCP URL: `https://proofbeforepay.vercel.app/gatecheck/mcp`\n- Transport: `streamable-http`\n- Public introspection: `initialize` and `tools/list`\n- Protected tool execution: bearer auth may be required for direct production calls\n- Product homepage: `https://proofbeforepay.vercel.app/gatecheck`\n- Scorecard: `https://github.com/LarryLemonBot/gatecheck/blob/main/scorecard.md`\n- Product card: `https://proofbeforepay.vercel.app/gatecheck/product-card.md`\n- Marketplace index: `https://proofbeforepay.vercel.app/gatecheck/marketplaces.json`\n\n## MCP Client Config\n\n```json\n{\n  \"mcpServers\": {\n    \"gatecheck\": {\n      \"type\": \"streamable-http\",\n      \"url\": \"https://proofbeforepay.vercel.app/gatecheck/mcp\"\n    }\n  }\n}\n```\n\nIf your client supports request headers and you have a GateCheck production token, add:\n\n```json\n{\n  \"Authorization\": \"Bearer YOUR_GATECHECK_TOKEN\"\n}\n```\n\nDo not put private keys, wallet secrets, cookies, customer data, or marketplace dashboard credentials into public metadata.\n\n## Tools\n\nGateCheck currently exposes six MCP tools:\n\n- `boundary_guard_check`\n- `scan_x402_resource`\n- `probe_x402_paid_path`\n- `check_agent_tool_readiness`\n- `generate_x402_launch_pack`\n- `generate_trust_receipt`\n\nPublic `tools/list` is available so buyers, agents, and directories can inspect the tool inventory before protected calls.\n\n## Buy through PayanAgent\n\nThese fixed-price offers settle in USDC through PayanAgent and automatically return the purchased GateCheck artifact:\n\n- [Quick x402 readiness check — $0.01 launch price](https://payanagent.com/marketplace/offers/kh738f3cbjbe89xhrtgzcxrg558agye2)\n- [Single-route launch pack — $9](https://payanagent.com/marketplace/offers/kh79mkywpaqdd5ca53hah5e1z98ahzg0)\n- [Service launch pack — $29](https://payanagent.com/marketplace/offers/kh7fw80665fqap3a8wq2pjx8wx8aghzc)\n- [Premium marketplace launch pack — $49](https://payanagent.com/marketplace/offers/kh76jzxdp8k5e3nr56ctp2c0qh8ag7jj)\n\nBuyer input is validated before PayanAgent presents the payment flow. Generated launch packs contain listing and approval-review artifacts; they do not publish listings, contact buyers, or claim marketplace endorsement.\n\n## What GateCheck Checks\n\n- Product-scoped discovery: homepage, `llms.txt`, `agents.txt`, product card, skill card, sitemap, and MCP server card.\n- MCP inventory: public initialize and tool-list introspection.\n- x402 behavior: unpaid `402` challenge metadata without submitting payment signatures or moving funds.\n- Listing readiness: buyer-facing copy, prices, evidence links, launch-pack artifacts, and claim boundaries.\n\n## Claim Boundary\n\nGateCheck reports and receipts prove observed public metadata, unpaid `402` behavior, request summaries, hashes, and returned artifacts only.\n\nThey do not prove marketplace endorsement, settlement, security certification, custody, KYC/AML coverage, buyer adoption, or downstream execution.\n\n## Product Boundary\n\nGateCheck is separate from Signal Desk and ResultRail.\n\nThis repository is the public distribution and marketplace-submission surface for GateCheck only.\n\n## Current Public Visibility\n\nVerified public surfaces include:\n\n- GateCheck remote MCP endpoint: `https://proofbeforepay.vercel.app/gatecheck/mcp`\n- Official MCP Registry: `https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.LarryLemonBot/gatecheck`\n- Smithery: `https://smithery.ai/servers/larrybuildsai/gatecheck`\n- Glama: `https://glama.ai/mcp/connectors/io.github.LarryLemonBot/gatecheck`\n- mcpservers.org: `https://mcpservers.org/servers/x402-resource-scanner-vercel-app-gatecheck-marketplaces`\n\nKnown external blockers: the former MCP.so listing URL currently returns `404`, and `https://xpay.tools/agents.txt` has not exposed `gatecheck`. Neither surface is claimed as live.\n\n## Marketplace Packet\n\n- Cline submission draft: `marketplaces/cline-submission.md`\n- MCP.Directory submission draft: `marketplaces/mcp-directory-submission.md`\n- Server manifest: `server.json`\n- Public scorecard: `scorecard.md`\n- Logo SVG: `assets/gatecheck-logo.svg`\n- Logo PNG: `assets/gatecheck-logo.png`\n",
