MCP Server: Simulate Cloud Infrastructure and Estimate Cost

Cloud World Model is a hosted streamable HTTP MCP server that lets coding agents simulate cloud infrastructure and estimate cost, latency, errors and resilience before deploying or changing infrastructure. It covers AWS, GCP, Azure, OCI and DigitalOcean. Simulations don't create resources in your cloud account.

Connect directly to the hosted endpoint

Add this Streamable HTTP URL as a remote MCP server in your compatible client.

Keyless demo configuration

Omit the API key to use the 9 keyless demo tools.

  "mcpServers": {
    "cloud-world-model": {
      "url": "https://www.cloudworldmodel.ai/mcp"
    }
  }
}

Authenticated configuration

Send your CWM API key in the x-api-key header to use all 64 authenticated tools.

{
  "mcpServers": {
    "cloud-world-model": {
      "url": "https://www.cloudworldmodel.ai/mcp",
      "headers": {
        "x-api-key": "<your CWM API key>"
      }
    }
  }
}

Full agent example

Working end-to-end agent example that simulates an infrastructure change before deployment in two parts: a small REST simulation paid per call with x402 on Base ($0.003, verified with a real paid run), and an advanced keyless MCP walkthrough showing a Redis cache failure before/after.

Optional: add directly in Cursor

Without an API key, 9 keyless demo tools are available. To unlock all 64 authenticated tools, add the x-api-key header.
