Connect Mercado Pago to Vercel AI SDK

Use KosmoKrator as a local integration gateway for Vercel AI SDK agents and scripts.

Create an MCP client that starts or connects to the KosmoKrator gateway for the selected integration. The gateway is local, scoped to this integration, and starts with --write=deny so Vercel AI SDK can inspect read-capable tools without receiving write access by default.

Mercado Pago MCP Config for Vercel AI SDK

Prefer CLI JSON calls when a workflow only needs one deterministic integration operation.

{
  "mcpServers": {
    "kosmokrator-mercado-pago": {

      "command": "kosmo",
      "args": [

        "--integration=mercado-pago",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually
