Perplexity Comet MCP

A production-grade MCP (Model Context Protocol) server that bridges Claude Code with Perplexity's Comet browser for autonomous web browsing, research, and multi-tab workflow management. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Perplexity Comet MCP

before you install - you'll need

COMET_PATH

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add rapiercraft-perplexity-comet-mcp -- npx -y perplexity-comet-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "rapiercraft-perplexity-comet-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "perplexity-comet-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
