Perplexity

Inject real IP math into Cursor Agent

The `validate_ip` tool feeds precise network boundaries directly into your active Cursor coding session via an MCP connection. Your editor's agent calls this tool to verify address syntax before writing database migrations or configuration files. Instead of relying on static mock data, Cursor uses the live output to generate working network code. This prevents broken firewall configurations from hitting your repository.

Automate subnet calculations in your editor

The `validate_ip` tool computes broadcast addresses and host ranges on the fly. When you edit a Kubernetes manifest, Cursor runs the math to ensure your pod subnets do not overlap. Setting up this MCP Server in your .cursor/mcp.json file takes ten seconds. Once active, the editor's autocomplete respects your actual network topology.

Debug invalid routing tables instantly

The `validate_ip` tool flags structural errors in complex IPv6 strings. Ask Cursor to audit your routing tables, and it will run each entry through the local validator. You catch malformed subnets before they deploy to staging. Your MCP agent pinpoints the exact bit where your CIDR mask breaks.

Setup guide

Set up IP & CIDR Validator MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the IP & CIDR Validator MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent IP & CIDR Validator transactions." If the MCP tools are loaded correctly, Cursor will call the IP & CIDR Validator tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "ip-cidr-validator-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about IP & CIDR Validator MCP in Cursor

Add the MCP Server to your .cursor/mcp.json file in your project root. Cursor detects the validate_ip tool immediately, allowing the editor's agent to run offline math on your code.

No, the validation runs locally and takes less than 5 milliseconds. Cursor executes the tool in the background without blocking your editor UI or code generation.

Yes, the agent calls the tool to verify boundary cases for your network code. It generates accurate test suites using valid IPv4 and IPv6 ranges calculated by the server.

No, the server performs all binary calculations offline. Your agent can validate subnets even when you are working without network access.

All IP addresses, CIDR blocks, and subnet masks processed by Cursor are evaluated in a zero-trust local sandbox. No external telemetry is generated, keeping your corporate network topology completely hidden from third-party APIs.
