Self-hosted MCP proxy that puts an x402 paywall in front of an existing MCP server
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
npx -y @cryptoapis-io/mcp-x402-accept
MCP client config

"command": "npx",
