# Composer Kit MCP Server

A Model Context Protocol (MCP) server for accessing Composer Kit UI components documentation, examples, and usage information. This server provides comprehensive access to the Composer Kit React component library designed for building web3 applications on the Celo blockchain.

## Installation

1. Clone the repository:

```bash
git clone https://github.com/celo-org/composer-kit-mcp
cd composer-kit-mcp
```

2. Install dependencies:

```bash
pip install -e .
```

## MCP Client Setup

### Setting up in Cursor

1. **Install the MCP server** (if not already done):

   ```bash
   pip install composer-kit-mcp
   ```

2. **Configure Cursor** by adding the MCP server to your Cursor settings:

   - Open Cursor Settings (Cmd/Ctrl + ,)
   - Navigate to "Features" → "Model Context Protocol"
   - Add a new MCP server with the following configuration:

   ```json
   {
     "mcpServers": {
       "composer-kit-mcp": {
         "command": "uvx",
         "args": ["composer-kit-mcp"]
       }
     }
   }
   ```

3. **Restart Cursor** to load the MCP server

4. **Verify the setup** by asking Cursor about Composer Kit components:
   - "What Composer Kit components are available?"
   - "Show me how to use the Wallet component"
   - "Search for payment-related components"

### Setting up in Claude Desktop

1. **Install the MCP server** (if not already done):

   ```bash
   pip install composer-kit-mcp
   ```

2. **Locate your Claude Desktop config file**:

   - **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
   - **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

3. **Edit the config file** to add the MCP server:

   ```json
   {
     "mcpServers": {
       "composer-kit-mcp": {
         "command": "uvx",
         "args": ["composer-kit-mcp"]
       }
     }
   }
   ```

   If the file doesn't exist, create it with the above content.

4. **Restart Claude Desktop** to load the MCP server

5. **Verify the setup** by asking Claude about Composer Kit:
   - Look for the 🔌 icon in the chat interface indicating MCP tools are available
   - Ask: "What Composer Kit components can you help me with?"
   - Try: "Show me examples of using the Payment component"

### Alternative Installation Methods

#### Using pipx (Recommended for isolation)

```bash
# Install pipx if you haven't already
pip install pipx

# Install composer-kit-mcp in an isolated environment
pipx install composer-kit-mcp

# The command will be available globally
composer-kit-mcp
```

#### Using virtual environment

```bash
# Create a virtual environment
python -m venv composer-kit-mcp-env
source composer-kit-mcp-env/bin/activate  # On Windows: composer-kit-mcp-env\Scripts\activate

# Install the package
pip install composer-kit-mcp

# Use the full path in your MCP config
# e.g., /path/to/composer-kit-mcp-env/bin/composer-kit-mcp
```

### Troubleshooting

#### Common Issues

1. **Command not found**: Make sure the package is installed and the command is in your PATH

   ```bash
   which composer-kit-mcp  # Should show the path to the command
   ```

2. **Permission errors**: Try installing with `--user` flag or use pipx

   ```bash
   pip install --user composer-kit-mcp
   ```

3. **MCP server not connecting**: Check that the command path in your config is correct

   ```bash
   composer-kit-mcp  # Should start the server (will wait for input)
   ```

4. **Python version issues**: Ensure you're using Python 3.11 or higher
   ```bash
   python --version  # Should be 3.11+
   ```

#### Debugging

To test if the MCP server is working correctly:

```bash
# Test the server directly
echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | composer-kit-mcp
```

This should return a JSON response with the available tools.

## Usage

### Running the Server

```bash
# Run the MCP server
python -m composer_kit_mcp.server

# Or use the CLI entry point
composer-kit-mcp
```
