Best Automation Plugins, Skills, and MCP Servers in 2026
Research-backed automation plugins, skills, and MCP servers with platform availability and direct setup routes.

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.
What it isagent-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 useIts 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.
What it isn8n 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 useThis 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 needAn existing n8n instance; the agent works through your user’s permissions.
What it isBrowser 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 useReach 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.
What it isDesktop 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 useTurn 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.
What it isZapier 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 useThis 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 needA Zapier account with the actions you enable.
What it isA 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 useWhen 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 needA Make account; the free tier works, and scenario runs consume plan operations.
What it isBrowserbase 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 useUse 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.
What it isPipedream 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 useChoose 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 needA Pipedream account; it holds each app’s credentials for you.
