Unlocking the Full Potential of Claude Code: Custom Workflows, MCP Servers, and More

Claude Code has recently become incredibly affordable, now included in the $20 Pro and $200 Max plans instead of being billed purely on API usage. This pricing change has made Claude Code my go-to AI coding assistant. While many tutorials cover the basics, there are some powerful features and tips that can dramatically boost your productivity with Claude Code — and I’m excited to share them with you.

In this post, you’ll learn how to create custom workflows, integrate MCP servers like Sentry, use Claude Code seamlessly inside terminals like Cursor, and unlock the ultimate “Ultraink” mode for tackling your toughest coding challenges.

1. Create Custom Workflows (Custom Agents) with Slash Commands

One of the most underrated features of Claude Code is the ability to build custom workflows or custom agents using slash commands. These commands are essentially reusable prompts with dynamic arguments that you define once and use repeatedly to automate complex tasks.

How It Works:

• Inside Claude Code’s base directory, you create a commands folder.
• In this folder, you add markdown files (.md) that define your workflows.
• Each .md file contains a prompt template with placeholders for arguments.
• For example, a search_web.md file can include a prompt that searches the web for any query you provide.

Example Workflow:

• Create a file named explain_codebase.md.
• Write a prompt asking Claude Code to scan and explain your entire codebase in simple language.
• Restart Claude Code so it recognizes the new commands.
• Now, typing /explain_codebase will run this detailed explanation prompt automatically.

This saves you from rewriting common prompts repeatedly and lets you build a personalized AI toolkit tailored to your coding needs.

2. Use Claude Code Inside Cursor or Windsurf Terminals — With Multiline Prompt Support

If you develop inside terminals like Cursor or Windsurf, Claude Code integrates directly via the claud command. This lets you run Claude Code from the command line and receive real-time feedback, including error messages from your editor.

Important Tip:

• To avoid accidentally executing prompts when pressing Enter, enable cursor terminal key bindings using a special command unique to Cursor.
• This allows you to write multiline prompts cleanly by pressing Shift + Enter to add new lines without triggering execution.

This multiline editing feature dramatically improves your workflow by letting you structure complex prompts naturally within the terminal environment.

3. Integrate Powerful MCP Servers Like Sentry for Issue Management

Claude Code supports MCP servers, which extend its functionality by integrating with platforms like Sentry — a popular error tracking and issue management tool.

Why Use MCP Servers?

• They provide Claude Code with deep context about your codebase’s issues.
• AI agents can fetch detailed error reports and even suggest fixes using AI-powered assistants like Sentry’s SEIR.
• This transforms Claude Code into a programmable debugging tool that can automatically find and fix errors based on real project data.

How to Add an MCP Server:

1. Exit Claude Code.
2. Run a command such as:

claud MCP addJSON sentry '<JSON configuration here>'
3. Restart Claude Code.
4. Use /MCP commands to interact with the Sentry MCP server, like finding errors or fixing issues by providing an issue ID.

You can add multiple MCP servers this way, increasing Claude Code’s integration with your development ecosystem.

4. Plan Mode & Auto Accept Edits: Brainstorm and Automate

Claude Code now includes a Plan Mode, accessible by pressing Shift + Tab. This mode helps you brainstorm and organize your project ideas interactively inside Claude Code.

• Write down project plans or ideas.
• Claude Code fleshes out your thoughts and clarifies your workflow.
• You can save these ideas into a claude.mmd file, which acts as a rulebook guiding Claude Code’s behavior — including codebase rules, documentation, and specific instructions.

Additionally, Auto Accept Edits Mode lets Claude Code make changes to files autonomously without requiring your approval for every edit, perfect for hands-off automation once you trust your workflows.

5. Embed Claude Code Into AI Applications with the Claude SDK

Beyond coding, Claude Code can be embedded into AI applications using its SDK and GitHub app integration. This means you can build customized AI-powered tools and workflows by programmatically controlling Claude Code within your own apps.

6. Unlock the Full Power with the Keyword: Ultraink

Finally, the secret to pushing Claude Code to its maximum potential is using the keyword Ultraink. This special keyword tells Claude Code to operate at the highest power level, ideal for the hardest problems that standard usage can’t solve.

• Use Ultraink sparingly for complex or critical tasks.
• Claude itself references this keyword as a way to unlock enhanced capabilities.

Summary

Claude Code is more than just an AI coding assistant — it’s a highly customizable, integrable, and powerful tool when you know how to use its advanced features:

• Build reusable custom workflows with slash commands.
• Seamlessly integrate with terminals like Cursor, supporting multiline prompts.
• Add MCP servers like Sentry for powerful issue tracking and AI debugging.
• Use Plan Mode to brainstorm and Auto Accept Edits for automation.
• Embed Claude Code into your own AI apps using the SDK.
• Push the limits with the Ultraink keyword for your toughest coding challenges.

With these tips, you can become ten times more productive and fully harness the power of Claude Code.
