# CIDR IP Calculator MCP for AI Agents MCP

> CIDR IP Calculator handles IPv4 and IPv6 subnet math. It calculates network addresses, broadcast addresses, and host ranges instantly. Perfect for network engineers needing quick, error-free calculations without manual bitmasking or complex math.

## Overview
- **Category:** infrastructure
- **Price:** Free
- **Endpoint:** https://edge.vinkius.com/vk_preview_nstdpKcRDSz5tyHJFI7N4xYLknk0A0pKG4nFsuBY/mcp
- **Tags:** ipv4, ipv6, cidr, subnet, networking-tools, ip-addressing

## Description

Stop manual subnetting or relying on unreliable web calculators. This MCP lets your AI agent handle all the heavy lifting for IPv4 and IPv6 networking tasks. You can ask your agent to find the usable host range for a specific CIDR block or verify if an IP address belongs to a certain subnet during a network audit. By connecting this through Vinkius, you bring precise networking logic directly into your existing workflow in Claude or Cursor. It turns your AI client into a specialized networking tool that can automate much of your infrastructure planning and auditing without you ever leaving your editor.

## Tools

### cidr_calculate
Calculates the network address, broadcast address, and host counts for any CIDR notation input. It provides all essential boundary details instantly.

### ip_check
Checks whether a specific IP address is contained within a given subnet range. This allows for rapid verification of network membership.

## Prompt Examples

**Prompt:** 
```
What are the details for 192.1arg.1.0/24?
```

**Response:** 
```
For **192.168.1.0/24**:

| Property | Value |
| :--- | :--- |
| **Network Address** | 192.168.1.0 |
| **Broadcast Address** | 192.168.1.255 |
| **First Usable Host** | 192.168.1.1 |
| **Last Usable Host** | 192.168.1.254 |
| **Total Hosts** | 256 |
| **Usable Hosts** | 254 |
```

**Prompt:** 
```
Is 10.0.0.5 inside 10.0.0.0/8?
```

**Response:** 
```
Yes, **10.0.0.5** is within the range of **10.0.0.0/8**.
```

**Prompt:** 
```
Check if 2001:db8::1 is in 2001:db8::/32.
```

**Response:** 
```
Yes, **2001:db8::1** is within the range of **2001:db8::/32.
```

## Capabilities

### Calculate subnet boundaries
Get the network and broadcast addresses for any CIDR block.

### Identify host ranges
Find the first and last usable IP addresses in a range.

### Verify IP membership
Check if a specific address sits inside a designated subnet.

### Count available hosts
Determine exactly how many IPs are usable within a network segment.

## Use Cases

### Setting up a new VPC
You need to define subnets for a cloud deployment, so you ask your agent to calculate the usable host ranges for several CIDR blocks.

### Auditing firewall rules
An engineer needs to know if a specific IP is covered by an existing rule, and they use `ip enough` to confirm it immediately.

### IPv6 migration planning
During a transition to IPv6, you use the MCP to calculate large-scale network boundaries without manual errors.

### Troubleshooting connectivity
You suspect an IP is outside its intended subnet and ask your agent to verify the range membership.

## Benefits

- Stop making bitmasking errors by letting `cidr_calculate` handle the math.
- Speed up firewall rule creation by using `ip_check` to verify IP ranges instantly.
- Reduce context switching between your editor and external networking websites.
- Get precise host counts for IPv6 planning without complex manual steps.
- Automate network auditing tasks directly within your AI-driven workflow.

## How It Works

The bottom line is you get error-free network math without manual calculation.

1. Connect the CIDR IP Calculator to your preferred AI client via Vinkius.
2. Ask your agent for specific subnet details or IP verification tasks.
3. Receive precise, calculated networking data instantly in your chat window.

## Frequently Asked Questions

**How can I use CIDR IP Calculator for IPv6?**
You can perform all subnet calculations and boundary checks for IPv6 addresses just as easily as IPv4.

**Can CIDR IP Calculator help with firewall configuration?**
Yes, you can use it to verify if specific IPs fall within the ranges allowed by your security rules.

**Does CIDR IP Calculator work in Claude?**
Yes, once connected via Vinkius, you can perform all these calculations directly in your Claude chat.

**Is this MCP accurate for large subnets?**
It provides mathematically precise results for any valid CIDR notation, regardless of the subnet size.

**Can I automate network audits with CIDR IP Calculator?**
You can ask your agent to check multiple IPs against various ranges, making it a great tool for automated auditing.

**What can I calculate with the `cidr_calculate` tool?**
The `cidr_calculate` tool provides a complete breakdown of a CIDR range, including the network address, broadcast address, first and last usable host addresses, and the total number of available hosts.

**How do I check if an IP is part of a specific subnet?**
You can use the `ip_check` tool by providing both the target IP address and the CIDR notation you want to check against.

**Does this support IPv6?**
Yes, the server fully supports both IPv4 and IPv6 subnet calculations and range checks.
