Activate this skill when:

• User asks about available tools or capabilities
• User wants to know if Claude can do something
• User mentions "MCP", "plugin", "integration", or "tool"
• User seems uncertain about how to accomplish a task
• User asks "is there a way to..." or "can you..."

Tool Discovery Process

When a user needs a tool that isn't currently available:

Step 1: Understand the Need

Ask clarifying questions:

• What specific task are you trying to accomplish?
• What data/services do you need to interact with?
• What format is the input/output?

Step 2: Search Existing Resources

Check these locations for potential solutions:

1. MCP Registry - Search official MCP servers:

``bash # Search the MCP registry on GitHub gh search repos "mcp server" topic:mcp ``

1. Claude Plugins Marketplace:

``bash # Check official plugins ls ~/.claude/plugins/marketplaces/claude-plugins-official/plugins/ ls ~/.claude/plugins/marketplaces/claude-plugins-official/external_plugins/ ``

1. Awesome MCP Servers: Search https://github.com/punkpeye/awesome-mcp-servers

1. NPM/PyPI for MCP:

```bash # Search npm for MCP servers npm search mcp-server

# Search PyPI pip search mcp ```

Step 3: Present Options

Once you find relevant tools:

1. Describe the tool: What it does and how it helps
2. Installation method: How to install it
3. Configuration needed: What setup is required
4. Example usage: Show how it would solve the user's problem

Step 4: Offer Installation Assistance

Ask the user:

• "I found [tool name] that can [capability]. Would you like me to help install it?"
• Provide installation commands
• Help configure .mcp.json or plugin settings

How to Install New MCP Servers

Method 1: NPM-based MCP Server

# Install globally
npm install -g @modelcontextprotocol/server-NAME

# Add to ~/.claude.json

Then add configuration to ~/.claude.json:

{
  "mcpServers": {
    "server-name": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-NAME"],
      "env": {
        "API_KEY": "your-key-here"
      }
    }
  }
}

Method 2: Python MCP Server

# Install with pip
pip install mcp-server-NAME

# Add to ~/.claude.json

Configuration:

{
  "mcpServers": {
    "server-name": {
      "command": "python",
      "args": ["-m", "mcp_server_name"],
      "env": {
        "API_KEY": "your-key-here"
      }
    }
  }
}

Method 3: Custom MCP Server

# Clone repository
git clone https://github.com/org/mcp-server-name
cd mcp-server-name
npm install

# Add to ~/.claude.json with full path

Search Strategy

When searching for a tool:

1. Start broad: "mcp server for [use case]"
2. Check official sources: Anthropic's MCP registry, official plugins
3. Search GitHub: gh search repos "mcp [service name]"
4. Check awesome lists: awesome-mcp-servers, awesome-claude
5. Search package managers: npm, PyPI, crates.io

Example Interactions

User: "Can Claude access my Google Calendar?"

Response pattern:

1. "Let me search for a Google Calendar MCP server..."
2. Use WebSearch or gh search to find options
3. Present findings: "I found [X] MCP server that provides Google Calendar integration"
4. Explain installation and configuration
5. Offer to help set it up

User: "Is there a way to interact with Docker?"

Response pattern:

1. Check if docker MCP exists
2. Search GitHub/npm for docker MCP servers
3. Present options with pros/cons
4. Guide installation if user wants to proceed

User: "What tools do I have?"

Response pattern:

1. List core tools
2. List connected MCP servers with their capabilities
3. List installed plugins
4. Mention discovery capabilities: "I can also search for new tools if you need something specific"

Proactive Discovery

When you notice the user struggling with a task:

• Suggest: "This task might be easier with [tool]. Would you like me to search for an MCP server that can help?"
• Offer: "I can search the MCP registry for solutions if you'd like"

Important Notes

• Always verify tool compatibility before suggesting installation
• Check if tools require API keys or authentication
• Warn about security implications of tools that access sensitive data
• Prioritize official Anthropic MCP servers when available
• Test that installed tools work before declaring success

Quick Reference Commands

# Search MCP registry
