These extensions let an agent take real actions: drive a browser, run local commands, or reach thousands of connected apps. They save significant manual work, but their broad permissions make scope limits, isolation, and human review matter more than usual.

## [agent-browser](https://agent-browser.dev/) by Vercel Labs
Local CLI browser built for agents
600Kestimated installs
**What it is** agent-browser is a local command-line browser built for agents. It exposes a compact set of actions like navigate, snapshot, click, fill, screenshot, and extract, so an agent can inspect and drive web pages, and test web apps, without leaving your machine.
**When to use** Its appeal is staying local: the default path runs on your machine with no hosted-browser account. Just note that its domain limits and action confirmations are opt-in, so out of the box it can drive logged-in sessions and take consequential actions freely.

n8n logo
## [n8n](https://n8n.io/)
Building and running n8n workflows
250Kestimated installs
**What it is** n8n exposes your existing workflow instance to an agent through a built-in MCP server. The agent can find, run, test, build, and edit your workflows and data tables directly, rather than reaching them through a community-built wrapper.
**When to use** This suits teams whose automations already run in n8n, or who want an agent to build and validate workflows programmatically. Access stays tied to the connected user's permissions, but running a workflow defaults to its published production version, so test with care.
**What you need** An existing n8n instance; the agent works through your user's permissions.
Install ConnectorMCP
Browser Use logo
## [Browser Use](https://browser-use.com/)
General web browsing and form-filling
190Kestimated installs
**What it is** Browser Use gives an agent general-purpose control of a web browser: it navigates pages, clicks, fills forms, and pulls data from sites that offer no clean API. An optional managed cloud adds remote browsers, proxies, stealth, and CAPTCHA handling for harder targets.
**When to use** Reach for it when operating a website is the task itself and no official connector fits, such as QA, research, or scraping data behind a form. The local runtime is free, though model calls and hosted browsers add cost.
Install CLI
Desktop Commander logo
## [Desktop Commander](https://desktopcommander.app/)
Broad control of your own computer
170Kestimated installs
**What it is** Desktop Commander gives an agent broad control of your actual computer: running terminal commands, managing processes, editing files and code, and reading PDFs, Word documents, and spreadsheets. It folds shell work, file editing, and document analysis into a single session.
**When to use** Turn to it when an agent needs to range across files, commands, and documents beyond a normal coding sandbox, replacing several narrower tools. The catch is scope: by its own docs it is not sandboxed by default, so treat it as a high-permission setup.
Install PluginPluginMCP
Zapier logo
## [Zapier](https://zapier.com/mcp)
Actions across 9,000+ connected apps
150Kestimated installs
**What it is** Zapier turns your agent into a single action layer over more than 9,000 connected apps, all through one hosted service. Instead of wiring up each API yourself, the agent discovers and runs the specific actions you enable across your SaaS tools.
**When to use** This earns its place when an agent needs to act across many SaaS tools such as email, calendars, CRMs, and project trackers, and no first-party connector covers them. Worth budgeting for: each successful tool call currently consumes two Zapier tasks, so heavy use adds up.
**What you need** A Zapier account with the actions you enable.
Install PluginPluginPluginMCP
Make logo
## [Make](https://www.make.com/en/mcp)
Running your existing Make scenarios
80Kestimated installs
**What it is** A connection to your Make automation platform through the official cloud MCP, with publisher-maintained skills installable as a plugin. The agent can trigger and parameterize scenarios, inspect data stores and connections, and operate account resources across the thousands of apps Make integrates.
**When to use** When automations you already built in Make should become agent-callable tools rather than being reimplemented. MCP scopes govern what the agent can reach, and scenario runs can modify organization resources - scope the connection deliberately.
**What you need** A Make account; the free tier works, and scenario runs consume plan operations.
Install PluginMCP
Browserbase logo
## [Browserbase](https://www.browserbase.com/)
Local or cloud browsers on demand
75Kestimated installs
**What it is** Browserbase gives an agent a controllable browser that runs either locally or in the cloud. Locally it drives Chrome to navigate, fill forms, extract structured data, and test interfaces. The cloud version adds remote sessions, proxies, CAPTCHA handling, persistent state, and session recordings.
**When to use** Use the local mode for development and everyday browser tasks, and the cloud when you need managed infrastructure or production-scale runs. Because cloud sessions can record and retain authenticated pages, review its logging and retention settings before pointing it at sensitive accounts.
Install PluginPluginPluginMCP
Pipedream logo
## [Pipedream](https://pipedream.com/docs/connect/mcp/users)
Authenticated actions across 3,000 APIs
50Kestimated installs
**What it is** Pipedream is one managed connection that reaches more than 10,000 tools across over 3,000 APIs. It handles each app's authorization and credentials for you, so a single agent can chain actions across services, such as reading Stripe data and posting a Slack summary.
**When to use** Choose it when an agent needs authenticated actions across several apps and you would rather not self-host a server for each one. Because it can trigger destructive actions across whatever you connect, keep the enabled app set and OAuth scopes as narrow as the task allows.
**What you need** A Pipedream account; it holds each app's credentials for you.

→ Browser Use - general-purpose control, with an optional cloud for harder targets

→ agent-browser - a compact local CLI that stays on your machine

Most setups need one browser tool, not two. Testing your own app's UI is a coding job - Playwright lives on the Coding page.

Browsers at scale, or behind bot defenses?

→ Browserbase - managed cloud sessions with proxies, CAPTCHA handling, and recordings

Automating across your SaaS stack?

→ Zapier - one action layer over 9,000+ connected apps

→ Pipedream - 3,000+ APIs with credential handling done for you

→ Make - your existing Make scenarios as agent-callable tools

Already running workflows in n8n?

→ n8n - find, run, build, and edit your existing workflows directly

Beyond the browser - files, terminal, documents?

→ Desktop Commander - terminal, processes, files, and document reading in one session

It has broad access to your computer; keep review on consequential actions.
