Identify device and browser from User-Agent

What this connector unlocks

Equip your AI agent with real-time browser and device intelligence through the UserStack MCP server. This integration provides instant parsing of User-Agent strings to identify the device type (mobile, desktop, tablet), brand, operating system, and browser version. Your agent can also detect crawlers and bots with high precision. Whether you are auditing web traffic, personalizing user experiences, or researching device distributions, your agent acts as a dedicated technical analyst through natural conversation.

What you can do

UA Parsing — Decode complex User-Agent strings into structured device and browser data.
Bot Detection — Identify if a request is coming from a human user or a search engine crawler.
Technical Auditing — Verify the OS and browser capabilities of specific web clients.
Device Profiling — Retrieve brand and model information for mobile and desktop systems.

How it works

1. Subscribe to this server
2. Enter your UserStack Access Key (get it at userstack.com)
3. Start detecting User-Agents from Claude, Cursor, or any MCP-compatible client

Who is this for?

Web Developers — quickly debug and analyze User-Agent data for testing.
Security Analysts — identify suspicious agents or bot activity in web logs.
Digital Marketers — profile the technology used by website visitors.
Operations Teams — automate the classification of incoming web requests.

Frequently asked questions

Yes! Use the detect_user_agent tool. The response will include the device brand ('Apple') and the specific model or type if available in the UA string.

Yes. The underlying API identifies known crawlers like Googlebot or Bingbot. The agent will explicitly state if the detected agent is a crawler.

Currently, the detect_user_agent tool processes one string per call. You can ask your AI agent to perform sequential checks for a list of strings.
