User Agent Parser API does not always answer

Over the last week it answered 30.5% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

utility
utility_parse_user_agent
Use this when you need to parse a user agent string to identify the client's browser, OS, device type, and bot status. Returns fully structured data. 1. browser -- name and version (e.g. "Chrome 120.0") 2. os -- operating system name and version (e.g. "Windows 11") 3. device -- type (desktop, mobile, tablet), vendor, and model 4. engine -- rendering engine (Blink, Gecko, WebKit) 5. isBot -- boolean indicating if the UA belongs to a crawler/bot 6. botName -- name of the bot if detected (e.g. "Googlebot") Example output: {"browser":{"name":"Chrome","version":"120.0"},"os":{"name":"Windows","version":"11"},"device":{"type":"desktop","vendor":null,"model":null},"engine":"Blink","isBot":false,"botName":null} Use this FOR analytics pipelines that need to classify traffic by device or browser, detecting bot traffic in access logs, or adapting content based on client capabilities. Do NOT use for HTTP header analysis -- use utility_parse_http_headers instead. Do NOT use for web scraping -- use web_scrape_to_markdown instead. Do NOT use for SEO auditing -- use seo_audit_page instead.

User Agent Parser API — questions

Answers built from our own checks of this server.

What can User Agent Parser API do?
It exposes 1 tools, read directly from the server on our last check. Among them: utility_parse_user_agent. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is User Agent Parser API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 61 ms. The bar chart above shows every period we have measured.
The registry lists User Agent Parser API as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect User Agent Parser API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does User Agent Parser API need an API key?
No. User Agent Parser API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
Is User Agent Parser API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
