Web search in Cline and Roo Code with x402serps

Cline and Roo Code both support remote MCP servers with headers, but their type names differ: Cline uses streamableHttp, Roo Code uses streamable-http.

Cline

MCP Servers icon → Configure → Configure MCP Servers opens cline_mcp_settings.json:

{
  "mcpServers": {
    "x402serps": {
      "type": "streamableHttp",
      "url": "https://x402serps.com/api/mcp",
      "headers": {
        "X-Trial": "1"
      },
      "disabled": false
    }
  }
}

Roo Code

Project file .roo/mcp.json, or the global settings via MCP Servers → Edit Global MCP:

{
  "mcpServers": {
    "x402serps": {
      "type": "streamable-http",
      "url": "https://x402serps.com/api/mcp",
      "headers": {
        "X-Trial": "1"
      }
    }
  }
}

With card credits

In either file, replace the header with "Authorization": "Bearer xs_YOUR_KEY".

Pay per call with x402 instead: tool calls without a trial header or key return the x402 payment requirements, which an x402-aware client can pay in USDC on Base or Solana. Search is $0.004 a call. Buy a credit key on the pricing page.
