Perplexity's remote MCP server now supports OAuth authentication, allowing users to sign in with their Perplexity account instead of pasting an API key. The feature works with MCP clients that support OAuth, such as claude.ai, Claude Code, Cursor, or VS Code. API keys remain available for clients without OAuth support.

## Evidence

Verbatim from https://docs.perplexity.ai/docs/resources/changelog#september-2026:

> The remote Perplexity MCP Server now supports OAuth. Add https://api.perplexity.ai/mcp to any MCP client that supports OAuth, such as claude.ai, Claude Code, Cursor, or VS Code, and sign in with your Perplexity account instead of pasting an API key.
