FAQ from Perplexity MCP Zerver

How does authentication work?

No API key is required; the server uses browser automation to interact with Perplexity’s web interface. An optional Pro account login can be performed to unlock better models and higher limits.

What are the runtime prerequisites?

Bun runtime and Node.js 18+ (for TypeScript compilation) are required. The server is built with TypeScript and runs under Bun.

How is data privacy handled?

All processing is local: research results are stored in a local SQLite database, and browser profile data resides in the directory specified by PERPLEXITY_BROWSER_DATA_DIR.

What does the optional Pro account provide?

Logging in with a Perplexity Pro subscription grants access to GPT-5.1, Claude Sonnet 4.5, and other enhanced models, as well as higher usage limits.

Are there any limitations?

Stability depends on Perplexity’s website consistency. The project is intended for educational use only, and browser automation may break if the site changes.
