# MCP Setup

Configure Model Context Protocol (MCP) servers to extend Claude Code's capabilities with external tools like web search, file system access, and GitHub integration.

## Overview

MCP servers provide additional tools that Claude Code agents can use. This skill helps you configure popular MCP servers using the `claude mcp add` command-line interface.

## Step 1: Show Available MCP Servers

Present the user with available MCP server options using AskUserQuestion:

**Question:** "Which MCP server would you like to configure?"

**Options:**
1. **Context7** - Documentation and code context from popular libraries
2. **Exa Web Search** - Enhanced web search (replaces built-in websearch)
3. **Filesystem** - Extended file system access with additional capabilities
4. **GitHub** - GitHub API integration for issues, PRs, and repository management
5. **All of the above** - Configure all recommended MCP servers
6. **Custom** - Add a custom MCP server

## Step 2: Gather Required Information

### For Context7:
No API key required. Ready to use immediately.

### For Exa Web Search:
Ask for API key:
```
Do you have an Exa API key?
- Get one at: https://exa.ai
- Enter your API key, or type 'skip' to configure later
```

### For Filesystem:
Ask for allowed directories:
```
Which directories should the filesystem MCP have access to?
Default: Current working directory
Enter comma-separated paths, or press Enter for default
```

### For GitHub:
Ask for token:
```
Do you have a GitHub Personal Access Token?
- Create one at: https://github.com/settings/tokens
- Recommended scopes: repo, read:org
- Enter your token, or type 'skip' to configure later
```

## Step 3: Add MCP Servers Using CLI

Use the `claude mcp add` command to configure each MCP server. The CLI automatically handles settings.json updates and merging.

### Context7 Configuration:
```bash
claude mcp add context7 -- npx -y @upstash/context7-mcp
```

### Exa Web Search Configuration:
```bash
claude mcp add -e EXA_AP
