The Best MCP Skills for OpenClaw: 15 You Should Install Today

Quick Answer

MCP skills are what give your OpenClaw agent real capabilities beyond chatting. With over 13,700 skills on ClawHub, it can be overwhelming to know where to start. We have tested dozens of the most popular skills and narrowed it down to 15 essentials across five categories: research, communication, productivity, data, and development. Install these and your agent goes from a simple chatbot to a genuinely useful assistant.

How MCP Skills Work in OpenClaw

Every skill on ClawHub is an MCP server — a lightweight program that exposes a set of tools your agent can use. When you install a skill, OpenClaw connects to it, discovers what tools are available, and starts using them automatically when relevant. You do not need to tell your agent which skill to use for each task. It reads your request, looks at its available tools, and picks the right ones.

Each skill also includes a SKILL.md file that tells the agent when and how to use the tool effectively. This means skills are not just raw API wrappers — they include context and guidance that helps your agent make better decisions about when to use them.

Research and Web Skills

Web Search. This is arguably the most important skill you can install. It gives your agent the ability to search the internet and return current results. Without it, your agent is limited to what the model already knows from training. With it, your agent can answer questions about today's news, look up current prices, find recent articles, and research any topic in real time. If you only install one skill, make it this one.

Web Scraper. While web search finds pages, the web scraper reads them. This skill lets your agent visit any URL and extract the content. Combined with web search, it means your agent can find relevant pages and then actually read and understand them. Perfect for research tasks where you need more than a search snippet.

Wikipedia. A fast, reliable way for your agent to look up factual information. Wikipedia queries are faster and more structured than general web searches, making this ideal for quick fact-checking, getting overviews of topics, and grounding the agent's responses in verified information.

Communication Skills

Email Reader and Sender. Connect your email account and your agent can read incoming messages, search your inbox, draft replies, and send emails on your behalf. This is one of the highest-value skills for personal productivity. Set up rules like "summarise my unread emails every morning" or "draft a reply to any email from my team that asks a question."

Slack Integration. If your team uses Slack, this skill lets your agent read channels, post messages, respond to mentions, and summarise conversations. Particularly useful for staying on top of busy channels without reading every message yourself.

Telegram Bot. Many people use Telegram as their primary interface with OpenClaw. This skill handles the connection and lets your agent send rich messages including formatted text, images, and file attachments.

Productivity Skills

Calendar Manager. Connect your Google Calendar or Outlook calendar and your agent can check your schedule, create events, send invitations, and manage conflicts. Ask your agent "what does my week look like" or "schedule a 30-minute call with Sarah on Thursday afternoon" and it handles it.

Task Manager. Integrates with tools like Todoist, Asana, or Trello. Your agent can create tasks, update statuses, set due dates, and give you overviews of what is on your plate. Great for people who want to manage their to-do list through conversation.

Note Taker. This skill lets your agent create, read, and organise notes. Some versions integrate with Notion or Obsidian, while others use a simple local storage. Useful for capturing ideas, meeting notes, and reference information that your agent can recall later.

Data Skills

File Manager. Gives your agent the ability to read, write, and organise files on your system or cloud storage. It can process documents, extract information from PDFs, create spreadsheets, and organise your downloads folder. Essential for any agent that needs to work with files.

CSV and Spreadsheet Processor. If you work with data regularly, this skill lets your agent read spreadsheets, run calculations, filter data, create summaries, and generate simple reports. Ask your agent to "find the top 10 customers by revenue in this spreadsheet" and it will read the data and give you the answer.

Database Connector. For more technical users, this skill lets your agent query databases directly. Useful for pulling reports, checking records, and answering questions that require looking up structured data.

Development Skills

GitHub Integration. Connect your GitHub account and your agent can browse repositories, read code, create issues, review pull requests, and even suggest fixes. A favourite among developers who use OpenClaw as a coding assistant.

Code Runner. This skill lets your agent write and execute code in a sandboxed environment. It can run Python scripts, process data, generate charts, and solve computational problems. Powerful for data analysis, quick calculations, and prototyping.

Terminal Access. Gives your agent controlled access to run shell commands. This is a more advanced skill that should be configured with appropriate safety limits, but it enables your agent to manage servers, run builds, check system status, and automate DevOps tasks.

How to Install Skills

Installing skills in OpenClaw is straightforward. Browse ClawHub at the OpenClaw skills registry, find the skill you want, and follow the installation instructions. Most skills require adding a few lines to your OpenClaw configuration file and potentially setting up API credentials for the services they connect to.

If you are running OpenClaw on Tulip, many popular skills come pre-configured or can be enabled with a single click. Tulip handles the networking and authentication so you spend less time on setup and more time actually using your agent.

Tips for Managing Skills

Start small. Install three to five skills that match your most common tasks and get comfortable with them before adding more. Too many skills at once can slow down your agent's decision-making and increase the chance of it picking the wrong tool for a task.

Review what your agent is using. Most OpenClaw setups let you see which skills the agent called and why. Check this periodically to understand how your agent works and spot any skills it is not using that you can remove.

Keep skills updated. The ClawHub community is active, and skills get regular improvements. Check for updates periodically to get bug fixes and new features.

Frequently Asked Questions

Are all ClawHub skills free?

The skills themselves are free and open-source. However, some skills connect to external services that may have their own costs. For example, a web search skill might use an API that charges per query. The skill documentation will note any external costs.

Can I build my own skills?

Yes. If you know JavaScript or Python, you can build an MCP server and wrap it in a SKILL.md file for OpenClaw. The OpenClaw documentation has a guide for skill development, and you can publish your skill to ClawHub for others to use.

Do skills slow down my agent?

Each installed skill adds a small amount of context that the agent needs to process. With five to ten skills, the impact is negligible. With 50 or more, you might notice slower response times. The practical sweet spot for most people is 10 to 20 skills.

What if a skill does something I did not expect?

OpenClaw has a confirmation mode that asks for your approval before the agent takes certain actions. Enable this for sensitive skills like email sending or file deletion until you are confident your agent behaves as expected.
