Parse user agents to extract browser, OS, device, and bot detection.
Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
Scanned 8 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The user-agent-parser MCP server exposes 1 tool across a range of capabilities. Its published description reads: "Parse user agents to extract browser, OS, device, and bot detection". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates user-agent-parser C+ — the findings are worth reviewing before you connect an agent to it. Its most notable finding was "No authorization on a public remote server". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check user-agent-parser's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add user-agent-parser to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
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
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
The server accepts tool enumeration (and likely invocation) with no authentication.
