Browserbase MCP Server

Cloud browser automation via the Browserbase API: sessions with live-view debugging, AI web agents, persistent contexts, downloads, fetch/search, and serverless functions. Its 40 documented tools cover session, agent, downloads, context.

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

One of 41 MCP servers published from mindstone/mcp-servers. Stars and repository activity are shared across all of them. See all 41 →

01 · Install Browserbase

before you install - you'll need

Set BROWSERBASE_API_KEY before connecting.

Claude Code

claude mcp add mindstone-mcp-servers-connectors-browser -- npx -y @mindstone/mcp-server-browserbase

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mindstone-mcp-servers-connectors-browser": {
      "command": "npx",
      "args": [
        "-y",
        "@mindstone/mcp-server-browserbase"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package @mindstone/mcp-server-browserbase - published under the repo owner's npm scope (@mindstone)

registry namespace io.github.mindstone is GitHub-verified and matches the repo owner

03 · What Browserbase can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can save your Browserbase API key (host-persisted when a bridge is present), list projects (IDs, concurrency limits, default timeouts), get one project's details, and create a cloud browser session (billed per minute.

Capability map

Tools grouped from the project's README - what Browserbase lets an agent do.

Session

10 tools - e.g. Create a cloud browser session (billed per minute; returns connectUrl); Get a session's status and connectUrl; Release a session (REQUEST_RELEASE semantics; sessions also auto-expire)

create_session · get_session · end_session · get_session_debug_urls · get_session_logs · get_session_replays…

Agent

10 tools - e.g. Create a reusable agent (name, system prompt, result schema); Get an agent's prompt and result schema; Partially update an agent

create_agent · get_agent · update_agent · delete_agent · create_agent_run · list_agent_runs…

read & search

5 tools - e.g. List projects (IDs, concurrency limits, default timeouts); List sessions, filtered by status or userMetadata query; List agents (cursor-paginated, date-filterable)

list_projects · list_sessions · list_agents · list_downloads · list_certificates

Context

3 tools - e.g. Create a context for persisting cookies/storage across sessions; Get a context's details; Permanently delete a context

create_context · get_context · delete_context

Download

3 tools - e.g. Metadata (size, checksum, MIME type); Fetch the bytes as base64 (8MB inline cap); Permanently delete a download

get_download_info · get_download_file · delete_download

Extension

3 tools - e.g. Upload a zipped Chrome extension (sandboxed file read); Get an uploaded extension; Permanently delete an extension

upload_extension · get_extension · delete_extension

Certificate

3 tools - e.g. Upload a CA certificate for TLS-inspecting proxies; Get a certificate; Permanently delete a certificate

upload_certificate · get_certificate · delete_certificate

Project

2 tools - e.g. Get one project's details; Browser minutes and proxy bytes consumed

What can Browserbase do?

How do I install Browserbase?

Run `npx -y @mindstone/mcp-server-browserbase`. The README documents one environment variable (BROWSERBASE_API_KEY) to set first. Set BROWSERBASE_API_KEY before connecting. You can also paste the ready-made client config above.

Does Browserbase run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
