What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Touches key and credential files src/upload-validator.ts:104

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add perplexity-comet-mcp -- npx -y perplexity-comet-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "perplexity-comet-mcp": {
      "args": [
        "-y",
        "perplexity-comet-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.perplexity-comet-mcp]

  "mcpServers": {
    "perplexity-comet-mcp": {
      "args": [

      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: COMET_PATH (Custom path to Comet browser executable (optional)), COMET_PORT (Chrome DevTools Protocol port (default: 9223)). The author declared them in the registry entry; get the values from the project itself.

Perplexity Comet MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Perplexity Comet MCP?
Perplexity Comet MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package perplexity-comet-mcp was installed 126 times last week.
How do I connect Perplexity Comet MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls perplexity-comet-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Perplexity Comet MCP?
The npm package perplexity-comet-mcp was installed 126 times in the last week. Week over week that is +9%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Perplexity Comet MCP open source?
Yes — it is published under the MIT licence, written in TypeScript, 51 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
