See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-22 Evidence 5 linked sources Publisher Perplexity Licence MIT ↗ Revision c73c8561bbc2 Read what was—and wasn’t—checked ↓ “The official MCP server implementation for the Perplexity API Platform” Perplexity · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Separates direct search results from synthesized answers and longer research requests. - The current source maps answer/reason/research tools to managed Agent API presets, avoiding a stale assumption that every tool uses the older Sonar path. ### A good fit for - Finding current sources and then checking the original pages - Running an explicitly scoped research request from an existing MCP client ### Weigh up before choosing - Synthesized answers are model output, not verified facts. Inspect citations and primary evidence before using them. - The research tool does not expose the same domain/recency filter inputs as every other tool. Do not assume one filter applies across the server. - Local mode still sends requests and prompt content to Perplexity. Longer research requests consume API resources, and cancellation is best-effort. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - README.md, package metadata and server registry - Full src/server.ts tool schemas and request paths - LICENSE ### Our findings - The direct search path and Agent API preset dispatch were read from the implementation. - Filters, streaming and cancellation were reviewed statically; no API call, citation accuracy check or billing test was performed. ### Not established by this review - No MCP server or upstream package was installed or run. - No authenticated account, API request, client handshake or write operation was tested. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. Upstream setup instructions ↗ DOCUMENTED COMMAND npx -y @perplexity-ai/mcp-server Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - For local stdio, supply PERPLEXITY_API_KEY through the client’s secret/environment settings and launch the documented package. - Alternatively connect to https://api.perplexity.ai/mcp using the supported authenticated HTTP setup. - Use your client’s actual configuration schema; do not paste another client’s wrapper or store API keys in shared project files. - The publisher documents npx -yq for strict stdio clients if npm chatter disrupts initialization; use client logs to verify a clean handshake. ### Before you start - An active Perplexity API account/key and applicable API access - Node.js/npm for local mode, or a client supporting the hosted transport - Network access to Perplexity APIs ### Compatibility Claude Code · Codex · Cursor · VS Code · Kiro ### Implementation TypeScript ### Transports stdio · Streamable HTTP ### API key; local or hosted transport - Send queries and message content to Perplexity - Read returned search material or generated research output - Use API-key permissions and consume provider API resources ### Cost model MIT-licensed local implementation; Perplexity API billing/access and client/model usage are separate. No consumer-plan allowance is assumed. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource.
