How to identify client device info with your AI

Connect this MCP to your AI client to turn messy User-Agent strings into clean technical data. It handles the parsing so you can focus on the fix.

Short answer

How can I extract browser and OS details from a User-Agent string?

Your agent uses the parse_ua tool to break down raw strings into specific fields like browser version, OS, and device type. This gives you the exact environment details needed to replicate bugs. You'll see the technical breakdown below.

Where the data lands.

Parsed technical details.

The AI processes the raw string and organizes the output into these specific categories.

STRUCTURED

Clean technical specs

The AI uses parse_ua to pull out the browser, engine, and OS. You get a clean list of attributes instead of a long string.

TRIAGE

Bug pattern detection

Your agent identifies if a specific OS or browser version is causing errors. This helps you spot trends in your error logs.

REPLICATION

Environment matching

Get the exact device and version info needed to set up a local testing environment. This makes reproducing bugs much easier.

HUMAN

Manual verification

The AI provides the parsed data, but you decide if the device info explains the specific bug you're seeing in your logs.

The workflow

What your AI does when a string arrives.

The AI acts as a translator between messy logs and actionable intelligence.

  1. Ingest raw strings

    Your agent takes the messy User-Agent text you provide from your logs or chat.

    parse_ua

  2. Extract attributes

    The AI runs the parse_ua tool to isolate the browser, version, and operating system.

  3. Identify device type

    It determines if the user is on a mobile device, tablet, or desktop via parse_ua.

  4. Summarize findings

    The agent presents the parsed data in a readable format for your debugging session.

FAQ

How this task behaves.

  • 01

    Can the AI fix the bug for me?

    No. The AI only parses the device information. You have to use that data to fix the code yourself.

  • 02

    Does the AI change my original logs?

    No. The AI only reads the strings you provide to extract information. It doesn't modify your source files or logs.

  • 03

    Can it parse multiple strings at once?

    Yes, if you provide a list of strings in your prompt, the AI can process them using the tool.

  • 04

    What happens if the User-Agent is malformed?

    The tool will attempt to extract what it can, but if the string is completely unreadable, the AI will tell you it couldn't find any recognizable data.

  • 05

    Does this work with any AI client?

    Yes, it works with any MCP-compatible client like Claude, Cursor, or Windsurf.
