Introduction

Claude, the AI assistant created by Anthropic, recently received a major update that makes building AI agents significantly easier. This update, called mCP (model context protocol), essentially turns Claude into an API by allowing it to run its own servers. As a result, users can now automate tasks and build Claude-powered AI applications much faster and more easily than before.

In this comprehensive guide, we'll walk through the process of setting up Claude desktop with mCP and creating a multi-step AI agent that can perform complex tasks with just a single prompt. By the end, you'll understand how to leverage Claude's new capabilities to build powerful AI tools.

What is mCP and Why is it Important?

mCP stands for model context protocol. It provides a way for Claude to interact with external tools and applications, solving a core challenge in building AI agents - connecting them to external data sources and services.

With mCP, Claude can now:

Run its own servers
Interact with external APIs and tools
Perform multi-step tasks autonomously
Access and manipulate data from various sources

This update makes it much easier for developers and users to create Claude-powered AI applications and agents. Tasks that previously required complex coding can now be accomplished with simple prompts.

Setting Up Claude Desktop with mCP

Let's walk through the process of setting up Claude desktop with mCP capabilities:

1. Download and Install Claude Desktop

Go to the Claude download page
Download the appropriate version for your operating system (Mac or Windows)
Install Claude desktop on your computer
Open the application and log in to your Claude account

2. Create the Configuration File

We need to create a configuration file to enable mCP servers. Follow these steps:

Open a terminal or command prompt
Run the following command to open the correct folder:
```
open ~/Library/Application\ Support/Claude/
```
Create a new file called claude_desktop_config.json by running:
```
touch claude_desktop_config.json
```
Open this file in a text editor (e.g. VS Code, Sublime Text, or even Notepad)

3. Set Up Brave Search mCP

We'll start by enabling web search capabilities:

Go to the Brave Search API page
Sign up for an account or log in
Choose a subscription plan (the free tier is sufficient)
Generate an API key

Copy the following JSON into your claude_desktop_config.json file:

{
  "mcp_servers": [
    {
      "name": "Brave Search",
      "url": "https://api.search.brave.com/res/v1/web/search",
      "auth": {
        "type": "bearer",
        "token": "YOUR_API_KEY"
      }
    }
  ]
}

Replace YOUR_API_KEY with the API key you generated
Save the file

4. Set Up GitHub mCP

Next, we'll add GitHub integration:

Go to GitHub and create an account if you don't have one
Generate a personal access token:
- Go to Settings > Developer settings > Personal access tokens
- Click "Generate new token"
- Select the necessary permissions (repo, write:packages, read:user, user:email)
- Create the token and copy it

Add the following to your claude_desktop_config.json file:

{
  "mcp_servers": [
    {
      "name": "Brave Search",
      "url": "https://api.search.brave.com/res/v1/web/search",
      "auth": {
        "type": "bearer",
        "token": "YOUR_BRAVE_API_KEY"
      }
    },
    {
      "name": "GitHub",
      "url": "https://api.github.com",
      "auth": {
        "type": "bearer",
        "token": "YOUR_GITHUB_TOKEN"
      }
    }
  ]
}

Replace YOUR_GITHUB_TOKEN with your GitHub personal access token
Save the file

5. Restart Claude Desktop

Close and reopen the Claude desktop application
You should now see new mCP tools available in the interface

Creating a Multi-Step AI Agent

Now that we have Claude desktop set up with mCP capabilities, let's create a multi-step AI agent that can perform complex tasks with a single prompt.

The Prompt

We'll use the following prompt to demonstrate Claude's new capabilities:

Please do the following:
1. Make a simple HTML page
2. Create a repository called "new_society_test"
3. Push the HTML page to the new_society_test repo
4. Add a little CSS to the HTML page, then push it up
5. Make an issue suggesting we add more content
6. Make a branch called "feature"
7. Make that fix and push the change
8. Finally, make a pull request against the main branch with the changes

This prompt instructs Claude to perform multiple tasks that would typically require a human developer, including creating files, managing a Git repository, and using GitHub's features.

Executing the Multi-Step Task

Open Claude desktop and paste the prompt into the chat interface
Claude will ask for permission to use various mCP tools - approve these requests
Watch as Claude executes each step of the process:
- Creating an HTML file
- Setting up a GitHub repository
- Pushing code to the repository
- Adding CSS and updating the file
- Creating an issue on GitHub
- Making a new branch
- Implementing changes
- Creating a pull request

Reviewing the Results

After Claude completes the tasks, you can verify the results:

Go to your GitHub profile
Find the newly created "new_society_test" repository
Check the repository contents, issues, and pull requests

You'll see that Claude has successfully created a functional GitHub repository with HTML and CSS files, an open issue, and a pull request - all from a single prompt.

Understanding the Implications

The ability to perform complex, multi-step tasks with a single prompt represents a significant advancement in AI capabilities. Here are some key implications:

1. Increased Productivity

Developers and non-developers alike can now accomplish tasks that would typically take hours in just a few minutes. This can lead to dramatic increases in productivity across various fields.

2. Lowered Barriers to Entry

People with limited programming knowledge can now perform tasks that previously required extensive coding skills. This democratization of technology can lead to more innovation and creativity.

3. Rapid Prototyping
