Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`PERPLEXITY_API_KEY` Required, secret	Your Perplexity API key. Read at call time and sent only as an Authorization header to api.perplexity.ai; never logged or echoed.
`PERPLEXITY_AGENT_WAIT_SECONDS` Optional	How long a blocking call waits before handing back a response_id to collect later. Defaults to 55, just inside Claude Desktop's unconfigurable 60s tool-call timeout. Raise to 300 on clients without that limit.
