The Perplexity MCP Server has moved to version 1.0, switching its model-backed tools from the legacy Sonar models to Agent API presets. Tool names and response shapes are unchanged, and all three tools are faster and cheaper on average than their Sonar predecessors.
- perplexity_ask now uses the fast preset, perplexity_reason uses medium, and perplexity_research uses high.
- Long-running research now streams progress to MCP clients that request it, and cancelling an MCP request cancels the underlying run.
- The strip_thinking and reasoning_effort parameters have been removed from the tool schemas, since the Agent API emits no think tags and presets manage reasoning effort themselves. Clients that still send these parameters are ignored gracefully.
Details are in the changelog.
