Server: perplexity

Overview

Perplexity MCP provides web-connected research via Perplexity Sonar models.

SSoT: unified-mcp-system/configs/servers/core.yaml (perplexity)

Install / run

• Command: pnpm
• Args: ["dlx","-y","@jschuller/perplexity-mcp@2.0.1"]

Required env vars

• PERPLEXITY_API_KEY (secret)

Tools (policy in this repo)

Use the tools by intent (cost/latency):

• perplexity_ask: simple factual lookups from docs/APIs
• perplexity_reason: code generation + multi-step reasoning (default for engineering tasks)
• perplexity_research: exhaustive “deep research report” only when explicitly requested

Troubleshooting

• 401 / auth errors: verify PERPLEXITY_API_KEY.
• High cost: ensure you are not using perplexity_research unintentionally.
