More Details Connect to Claude

This MCP server provides deterministic tools for designing AWS VPC network architectures. Use get_vpc_layout to generate non-overlapping subnet CIDR blocks, network addresses, and usable IP counts across multiple availability zones. You can also use validate_subnet_integrity to check for CIDR overlaps and get_ip_summary to analyze total VPC capacity and utilization. It ensures all subnets adhere to AWS reserved IP rules and fit within your specified VPC CIDR.

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

get_ip_summary

Provides a high-level summary of the capacity and usage of the VPC

get_vpc_layout

Generates a complete, deterministic layout of all requested subnets within a given VPC CIDR

validate_subnet_integrity

Verifies that a provided set of subnet CIDR blocks is mathematically sound and does not overlap

Generate a VPC layout for 10.0.0.0/16 with 3 availability zones, including public, private, and database subnets with 100 required IPs each.

The VPC layout has been generated. Subnets are allocated sequentially: Public subnets in us-east-1a, 1b, and 1c, followed by Private and Database tiers. All subnets fit within 10.0.0.0/16.

Check if these CIDR blocks overlap: ['10.0.1.0/24', '10.0.1.128/25']

The CIDR blocks overlap. The range 10.0.1.128/25 is contained within 10.0.1.0/24.

What is the total usable IP count for a 10.0.0.0/24 VPC with one /26 subnet?

A /26 subnet has 64 total addresses. After subtracting the 5 AWS reserved IPs, there are 59 usable host IPs available.

The `get_vpc_layout` tool automatically subtracts 5 reserved IP addresses (network, VPC router, DNS, future use, and broadcast) from the total addresses in each subnet to provide an accurate usable IP count.
