SOLx402 MCP Server

  

SOLx402 MCP Server is a Model Context Protocol (MCP) server that enables AI assistants to interact with the x402 payment protocol on Solana. It provides tools for discovering and consuming x402-enabled services, managing USDC payments, querying protocol documentation, and accessing Solana development resources through integrated MCP clients.

⚠️ Important: Request Timeout Configuration

Critical Setup Requirement: When using this MCP server, it's essential to configure your MCP client with a minimum request timeout of 60,000ms (60 seconds) to ensure successful execution of x402 service consumption.

Why This Matters:

• x402 services are external APIs that may require significant proces
