Key Points

  • The article explains how to connect a pay-per-use MCP tool API (x711) to Claude Desktop and coding agents like Cursor, Cline, and Windsurf in under 30 seconds.
  • By adding a simple MCP server configuration (pointing to https://x711.io/mcp with streamable-http), users can restart/reload the app and immediately see new tools in the tool picker.
  • The MCP integration provides 29 additional capabilities, including real-time web search, live crypto price feeds, transaction simulation, shared memory, and LLM routing to select the cheapest model for a query.
  • It specifies where to place the configuration files for Claude Desktop (claude_desktop_config.json) and for project agents (e.g., .cursor/mcp.json or cline_mcp_settings.json), enabling consistent tool access across workflows.
