GateCheck by LarryBuildsAI is a Model Context Protocol (MCP) server: One-cent x402 and MCP readiness checks plus fixed-price marketplace launch packs. Because it speaks the Model Context Protocol, AI assistants can use GateCheck by LarryBuildsAI as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://proofbeforepay.vercel.app/gatecheck/mcp and you're connected, with nothing to install locally. The current release is v0.1.3, with source at LarryLemonBot/gatecheck on GitHub.
On mcp.site, GateCheck by LarryBuildsAI sits in the Finance category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
