This MCP server provides specialized tools to help developers predict performance characteristics in serverless environments. Use estimateLatencyImpact to calculate the difference between cold and warm start latencies based on runtime, package size, and memory allocation. The calculateColdStartProbability tool analyzes traffic patterns and idle timeouts to estimate how often a new execution environment will be initialized. Additionally, compareConcurrencyPricing allows for cost-effective analysis between on-demand and provisioned concurrency models by evaluating monthly requests and memory allocation.

Available Tools

3 tools expose this connector's capabilities to your AI agent.

compare_cost_models

Compares the monthly financial impact of On-Demand vs Provisioned Concurrency

estimate_latency_delta

g., nodejs, java), memory allocation in MB, and bundle size in MB. Calculates the estimated time difference between a cold start and a warm start

calculate_cold_start_probability

Estimates the percentage of requests that will trigger a cold start

What is the estimated latency impact for a 50MB Node.js function with 128MB of memory?

The cold start latency is approximately 212.8ms, while the warm start latency is 15.0ms, resulting in a latency delta of 197.8ms.

Calculate the cold start probability for a Python function with 3 requests per minute and a 300 second idle timeout under a spiky traffic pattern.

The estimated cold start rate is 3.33%.

Compare pricing for 10,000 monthly requests with a 200ms duration and 512MB memory. Should I use provisioned instances?

On-demand cost is approximately $0.0167, while provisioned concurrency would be significantly higher due to the hourly rate of provisioned instances.

The `estimateLatencyImpact` tool uses runtime-specific weights and considers your package size and memory allocation to calculate the latency delta. Tools available: `estimate_latency_delta`, `calculate_cold_start_probability`, `compare_cost_models`.
