Parse a User-Agent: browser, OS, device, plus bot, search crawler, AI crawler and AI agent flags.
Overview
AI-generated overview
Remote MCP endpoint that parses User-Agent strings into browser, OS, device, bot, crawler and AI agent details.
- What it does
- UAParse is a remote MCP server that takes a User-Agent string and returns a structured breakdown of it: browser, operating system and device, plus flags indicating whether the client is a bot, a search crawler, an AI crawler or an AI agent. It is exposed as a streamable HTTP endpoint, so an assistant connects to it directly rather than running anything locally. The registry description lists no individual tool names.
- When to use it
- Useful when an assistant needs to interpret raw User-Agent strings, for example when reviewing web server logs, debugging analytics or request data, or checking whether traffic comes from a bot or an AI crawler. It is a narrow, single-purpose service, so it is only worth adding if User-Agent interpretation comes up in your work.
- Requirements
- A remote streamable HTTP connection to the provider's endpoint; no local runtime or package is needed. An optional Authorization header of the form 'Bearer up_live_…' with a free API key, obtained by email request, raises rate limits; the service works without a key.
Before you install
The Authorization header carries an API key, so treat it as a secret and avoid exposing it in logs or shared configuration. User-Agent strings you submit are sent to a third-party remote service, which may be a concern if they contain sensitive or identifying request data.
Installation
