Get structured client details via MCP Server

Don't let your agent guess what kind of machine sent the logs. The `parse_ua` tool takes a raw User-Agent string and spits out clean JSON. This means you get exact identification for the Browser, OS, and Device. It keeps your local analysis accurate. Instead of relying on guesswork from log files—which is always sketchy—you pipe the UA string directly into Claude Desktop and get structured data you can use immediately.

Validate IT logs with `parse_ua`

When debugging, you're always dealing with messy text. Running `parse_ua` makes sense because it instantly decodes those raw HTTP User-Agent strings. It pulls out the Browser, OS, and Device data into structured JSON that your script can actually read. This tool is key for accurate IT log analysis. You feed it the string from a server log, run the function, and suddenly you've got reliable client specs without any hallucination risk.

Improve local debugging with MCP Server

Since you're working locally on your machine, running `parse_ua` means you can test against simulated log data. You pass the string through and get structured JSON for Browser, OS, and Device identification. This helps you build robust scripts that don't break when client specs change or when logs are incomplete. It’s a reliable way to ground your local development.
