Connect

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions

What is the Perplexity MCP server?

The official MCP server implementation for the Perplexity API Platform

What tools does Perplexity expose?

4 in total: 4 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Perplexity safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Perplexity need?

It reads PERPLEXITY_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Perplexity run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @perplexity-ai/mcp-server at 0.2.0.

How current is this page?

The grade is for one exact copy of the source (0ed911c73ae0), read on 2026-09-22. The repository is watched and re-audited when it changes.
