Boundary Guard x402 is a Model Context Protocol (MCP) server: MCP tools for x402 readiness, paid-path probes, launch packs, and trust receipts. Because it speaks the Model Context Protocol, AI assistants can use Boundary Guard x402 as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://x402-resource-scanner.vercel.app/mcp and you're connected, with nothing to install locally. The current release is v0.1.0.
On mcp.site, Boundary Guard x402 sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
