MCP Server: Simulate Cloud Infrastructure and Estimate Cost

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.

    }
  }
}

Authenticated configuration

Send your CWM API key in the x-api-key header to use all 69 authenticated tools.

The 9 keyless demo tools let you explore scenarios, create and step capped simulations, change traffic, fail and recover resources, inspect metrics, and delete demos; all 69 authenticated tools additionally support advanced chaos experiments, multi-cloud comparisons, AI analysis, and reinforcement-learning workflows.

Try this first

Run these prompts in order in the same conversation using the keyless demo tools: first establish a baseline, then test a failure in that simulation (6 steps total).

Use Cloud World Model to simulate a fixed 3-node AWS compute cluster behind a load balancer at 300 requests/second, with autoscaling disabled. Advance 3 steps and report modeled p99 latency, error rate, and hourly cost; state assumptions or unavailable metrics.

2. Compare a node failure

In that simulation, keep traffic at 300 requests/second, fail one compute node, advance 3 steps, and compare modeled p99 latency, error rate, and hourly cost with the baseline. Explain any unavailable metrics or incomplete cost estimates.

Create an API key

Get a CWM API key from the account setup page.

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 69 authenticated tools, add the x-api-key header.
