Cómo conectar x402 Universal Payer

x402 Universal Payer se ejecuta en local a partir de un paquete de Node.js publicado en el registro npm: @three-ws/mcp-bridge, versión 1.0.2. Usa MCP mediante stdio, así que el cliente lo inicia como programa y se comunica con él a través de la entrada y salida estándar. Necesita Node.js; los clientes suelen iniciarlo con npx - el comando habitual es npx -y @three-ws/mcp-bridge@1.0.2. Lee estas variables de entorno: MCP_BRIDGE_EVM_PRIVATE_KEY (secreto), MCP_BRIDGE_SVM_PRIVATE_KEY (secreto), MCP_BRIDGE_MAX_PRICE_PER_CALL_ATOMIC, MCP_BRIDGE_MAX_TOTAL_ATOMIC, MCP_BRIDGE_ALLOWED_PAYTO, MCP_BRIDGE_ALLOWED_HOSTS, MCP_BRIDGE_ALLOW_HTTP, MCP_BRIDGE_DISCOVER_LIMIT, MCP_BRIDGE_BAZAAR_URL, MCP_BRIDGE_BATCH_DEPOSIT_MULTIPLIER, MCP_BRIDGE_MAX_DEPOSIT_ATOMIC, X402_MCP_BRIDGE_CHANNELS_DIR y RPC_URL_8453; hay que definirlas en la configuración del cliente para este servidor.
