What is the UserStack User-Agent Lookup MCP Server?
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.

Frequently asked questions
Can I identify if a user is on an iPhone?
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.
Does this server detect search engine bots?
Yes. The underlying API identifies known crawlers like Googlebot or Bingbot. The agent will explicitly state if the detected agent is a crawler.
Can I parse multiple User-Agents at once?
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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
