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.

About 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.

Pydantic AI validates every UserStack User-Agent Lookup tool response against typed schemas, catching data inconsistencies at build time. Connect 1 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

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.

UserStack User-Agent Lookup + Pydantic AI FAQ

Common questions about integrating UserStack User-Agent Lookup MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your UserStack User-Agent Lookup MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
