Add the Perplexity MCP server to Windsurf

Config last verified Jun 1, 2026

The exact config to run Perplexity in Windsurf — paste it in, restart, and the tools load.

Prerequisites

Windsurf installed.
PERPLEXITY_API_KEY — Perplexity API key from the dashboard at perplexity.ai/account/api. Required.

Setup

1. Open `~/.codeium/windsurf/mcp_config.json`

On Windows the file lives at %USERPROFILE%\.codeium\windsurf\mcp_config.json.

2. Add this configuration

Add to ~/.codeium/windsurf/mcp_config.json

~/.codeium/windsurf/mcp_config.json

json

{
  "mcpServers": {
    "perplexity": {
      "command": "npx",
      "args": [
        "-y",
        "@perplexity-ai/mcp-server"
      ],
      "env": {
        "PERPLEXITY_API_KEY": "<PERPLEXITY_API_KEY>",
        "PERPLEXITY_BASE_URL": "<PERPLEXITY_BASE_URL>",
        "PERPLEXITY_TIMEOUT_MS": "<PERPLEXITY_TIMEOUT_MS>"
      }
    }
  }
}

3. Restart Windsurf and confirm the Perplexity tools load.

Gotchas

Windsurf's Cascade reads MCP servers from an "mcpServers" object in ~/.codeium/windsurf/mcp_config.json. Unlike most clients, remote servers are configured with the "serverUrl" field rather than "url", so a config that uses "url" silently fails to connect. Native remote transport is supported without an OAuth flow.
