AI review

This is the official Perplexity MCP server. It reads the PERPLEXITY_API_KEY from the environment and makes outbound calls to api.perplexity.ai, which is exactly what it advertises. There are no hidden instructions, deceptive tool descriptions, or exfiltration mechanisms. The HTTP transport security model is clearly documented with appropriate warnings about exposing the server beyond loopback.

Scanning every extension your team installs?

Pro & Team add monitoring, private scans, and a CI gate for unsafe extensions.

MCPVet is a heuristic aid, not a security guarantee. A clean grade does not prove an extension is safe; always review code and instructions you don't trust.
