Search Perplexity using your browser login. Returns answers, sources, and thread URLs. No API key.
Overview
AI-generated overview
Lets an assistant run Perplexity searches through a local browser login, returning answers, sources, and thread URLs without an API key.
- What it does
- This local MCP server drives a Chromium-based browser session to query Perplexity and returns the generated answer, the cited sources, and links to the resulting threads. It relies on an existing browser login rather than an API key, and can optionally store its login profile in a chosen directory.
- When to use it
- Useful when you want an assistant to pull Perplexity answers and citations into its workflow but you do not have or want to use a Perplexity API key. It fits desktop setups where a logged-in browser session is acceptable.
- Requirements
- Runs locally as a stdio process, typically started with npx from the npm package perplexity-browser-mcp. Requires a desktop environment with a Chromium-based browser and a signed-in Perplexity account. The optional environment variable PERPLEXITY_PROFILE_DIR sets an absolute directory for the local login profile.
Before you install
It reuses your Perplexity browser login, so the assistant acts under your account and its queries and results may be tied to that session. The local login profile directory can contain session credentials; keep it private. Searches are sent to Perplexity as a third party, and it is desktop-only, so it will not run in a headless or web-only environment.
Installation
In SourceWeft
- Open Perplexity Browser MCP in the dashboard and add it to a workspace.
