How to audit firewall rules with your AI

Connect this MCP to your agent to cross-reference network logs against your permitted IP ranges.

Ask AI about this page

Short answer

Can my AI check if IPs in my logs are allowed?

Yes. Your agent uses the validator to see if specific IP addresses fall within your defined CIDR blocks. You'll get a clear list of matches and mismatches to review.

Audit outcomes

Where your results land.

The AI processes your raw data and organizes the findings into these categories.

MATCH

Permitted traffic

The agent identifies IPs that fall within your allowed CIDR ranges. These are flagged as safe hits.

MISMATCH

Unauthorized access

The AI finds IP addresses that don't belong to your permitted blocks. These are your primary security targets.

ERROR

Invalid data

The agent catches malformed IP addresses or broken CIDR strings that prevent a clean audit.

HUMAN

Manual review

You decide how to handle the flagged mismatches. The AI identifies the outliers, but you manage the firewall updates.

The workflow

What your AI does when the logs arrive.

The agent handles the heavy lifting of mathematical range checking so you don't have to.

  1. Ingest logs

    Your agent reads the IP addresses from your provided log files or text snippets.

    validate_ip

  2. Compare ranges

    The agent checks every IP against your list of CIDR blocks to see if they overlap.

    validate_ip

  3. Identify outliers

    The AI isolates any IP that sits outside your permitted network boundaries.

    validate_ip

  4. Report findings

    The agent summarizes the hits and misses into a readable format for your review.

    validate_ip

FAQ

How the audit behaves

  • 01

    Can the AI change my firewall rules?

    No. The AI only validates the data. You must manually update your firewall settings based on the results.

  • 02

    Does the AI delete any of my logs?

    No. The agent only reads the data you provide to perform the validation.

  • 03

    Can it handle IPv6?

    Yes, the tool validates both IPv4 and IPv6 addresses against their respective CIDR blocks.

  • 04

    Will it automatically block bad IPs?

    No. The AI identifies the mismatches, but it has no capability to interact with your network hardware or software.

  • 05

    Can I upload a whole CSV file?

    You can paste the contents of your CSV or log file directly into the chat for the agent to process.
