X402 Payment Safety is a Model Context Protocol (MCP) server: Authorize x402 payments before signing with request-bound, signed safety decisions. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://agent-guild-5d5r.onrender.com/mcp/payment-safety/ and you're connected, with nothing to install locally. The current release is v2.5.42, published under the Apache-2.0 license, with source at AgentTanuki/agent-guild on GitHub.
You'll find X402 Payment Safety in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
