Lists all available chat conversations with Perplexity AI. Returns chat IDs, titles, and creation dates (displayed in relative time format, e.g., "5 minutes ago", "2 days ago"). Results are paginated with 50 chats per page.
AI agents call list_chats_perplexity to retrieve information from Perplexity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about existing chat conversations without modifying, creating, or deleting any data. It has no side effects beyond querying and displaying information. The only potential concern is information disclosure (listing all chats might reveal conversation existence), but the blast radius is minimal and the operation is purely informational. Classified as Read with low severity.
From the tool's definition Tool description states it 'Lists all available chat conversations' and 'Returns chat IDs, titles, and creation dates'. The verb 'lists' and the retrieval-only nature (no modification, deletion, or execution) clearly indicate a read operation.
