What the publisher says

From the Perplexity Agent repository's README, as published. We do not edit it. Read it on GitHub

perplexity-agent-mcp

A single-file, zero-third-party-dependency MCP server for Perplexity's Agent API — multi-step web research with citations, exposed to any MCP client over stdio.

Python standard library only: no MCP SDK, no HTTP library, no code generated at build time. perplexityagentmcp.py holds your API key and talks to the network on your behalf, so it is written to be read — 1,774 lines, comments included. Both install paths below ship the exact same file; which one you pick changes how many other parties you're trusting to get it onto your disk, not what actually runs.

Background reading: perplexity-agent-mcp: an open-source MCP server for Perplexity's Agent API — why this exists, what the Agent API does that Sonar doesn't, and what building it turned up.

Why this exists

Perplexity's own @perplexity-ai/mcp-server wraps the Sonar chat models and the Search API. It does not reach the Agent API (POST /v1/agent) — Perplexity's multi-step, tool-using research endpoint, which runs its own web searches, fetches pages, and synthesizes one cited answer. This server fills exactly that gap. It's meant to run alongside the official one, not replace it.

The three tools

The Agent API is asynchronous under the hood (see Configuration for why that matters), so this server exposes it as one lifecycle, not one call:
