graded-x402 is a Model Context Protocol (MCP) server: Discover and call 2,000+ x402 machine-payable services through one graded API key + gateway. In practice that means any MCP-compatible AI assistant can call graded-x402's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://graded.sh/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
graded-x402 is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
