Browserbase

Q: Is Browserbase a remote or a local server?

Remote. Browserbase hosts it at https://mcp.browserbase.com/mcp, and it speaks Streamable HTTP. There's nothing to install.

Q: What can Browserbase do?

It has 6 tools, including start, end and navigate. You can create or reuse a Browserbase browser session, navigate to a URL in a cloud browser and perform natural-language actions on a page.

Control cloud browsers through Stagehand: navigate pages, act on elements, observe the page and extract data.

listing.about

Connects an assistant to Browserbase cloud browser sessions using Stagehand. It can start a session, open URLs, perform actions on a page, list actionable elements and extract data from what is on screen.

Runs as a hosted streamable HTTP endpoint at https://mcp.browserbase.com/mcp. The operator notes say a Browserbase API key is passed as the query parameter browserbaseApiKey. The older self-hosted npm package (@browserbasehq/mcp-server-browserbase) needs Browserbase and Gemini keys, and its repository is archived.

Claude Code

Run this in a terminal, in your project folder:

claude mcp add --transport http browserbase https://mcp.browserbase.com/mcp

Start Claude Code and type /mcp. browserbase should show as connected.

Browserbase needs an API key. Browserbase's docs say which header carries it; most servers use Authorization: Bearer <YOUR_API_KEY>.

Claude Desktop

Custom connectors can't send this server's key header, so use the mcp-remote bridge. Open Settings → Developer → Edit Config and add:

claude_desktop_config.json

{
  "mcpServers": {
    "browserbase": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.browserbase.com/mcp"
      ]
    }
  }
}

Replace the placeholder with your key and restart Claude Desktop.

The bridge needs Node.js on your computer.

Cursor

Add to Cursor a11y.new_tab

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json

{
  "mcpServers": {
    "browserbase": {
      "url": "https://mcp.browserbase.com/mcp"
    }
  }
}

Browserbase needs an API key. Browserbase's docs say which header carries it; most servers use Authorization: Bearer <YOUR_API_KEY>.

VS Code

Install in VS Code a11y.new_tab

Or from a terminal:

code --add-mcp '{"name":"browserbase","type":"http","url":"https://mcp.browserbase.com/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json

{
  "servers": {
    "browserbase": {
      "type": "http",
      "url": "https://mcp.browserbase.com/mcp"
    }
  }
}

Browserbase needs an API key. Browserbase's docs say which header carries it; most servers use Authorization: Bearer <YOUR_API_KEY>.

Devin Desktop

Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):

mcp_config.json

{
  "mcpServers": {
    "browserbase": {
      "serverUrl": "https://mcp.browserbase.com/mcp"
    }
  }
}

Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add browserbase --url https://mcp.browserbase.com/mcp

Or edit ~/.codex/config.toml directly:

config.toml

[mcp_servers.browserbase]
url = "https://mcp.browserbase.com/mcp"

Browserbase needs an API key. Browserbase's docs say which header carries it; most servers use Authorization: Bearer <YOUR_API_KEY>.

Gemini CLI

gemini mcp add --transport http browserbase https://mcp.browserbase.com/mcp

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI's settings file.

{
  "mcpServers": {
    "browserbase": {
      "type": "http",
      "url": "https://mcp.browserbase.com/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.browserbase.com/mcp.

Browserbase needs an API key. Browserbase's docs say which header carries it; most servers use Authorization: Bearer <YOUR_API_KEY>.

listing.faq

Can I paste mcp.tc/i/browserbase into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.browserbase.com/mcp, so your client talks to Browserbase directly. Your key goes there too, never to mcp.tc. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Browserbase need an API key or a sign-in?

Yes. Browserbase needs an API key. Get one from Browserbase and keep it in your client's config, never in a shared file.

Is Browserbase a remote or a local server?

Remote. Browserbase hosts it at https://mcp.browserbase.com/mcp, and it speaks Streamable HTTP. There's nothing to install.

What can Browserbase do?

It has 6 tools, including start, end and navigate. You can create or reuse a Browserbase browser session, navigate to a URL in a cloud browser and perform natural-language actions on a page.

Which clients can use it?

Any client that supports remote MCP servers and can send your key: Claude Code, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others, and Claude Desktop through the mcp-remote bridge. claude.ai and ChatGPT can't send a key, so they can't use it.

Who wrote this page?

mcp.tc's robot read Browserbase's own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
