## Installation

### For MCP Server Usage (Recommended)

**Using uvx (no installation required):**

The easiest way to use this as an MCP server - just configure in Claude Desktop:

```json
{
  "mcpServers": {
    "mcp-server-generator": {
      "command": "uvx",
      "args": ["hitoshura25-mcp-server-generator"]
    }
  }
}
```

**Prerequisites:** Install [uv](https://docs.astral.sh/uv/):
```bash
# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
```

### For CLI Usage (Alternative)

**Using pipx (isolated installation):**

```bash
pipx install hitoshura25-mcp-server-generator
```

**Using pip:**

```bash
pip install hitoshura25-mcp-server-generator
```

### From Source (Development)

```bash
git clone https://github.com/hitoshura25/mcp-server-generator.git
cd mcp-server-generator
pip install -e .
```

## Quick Start

### Interactive Mode (Recommended)

The easiest way to get started:

```bash
hitoshura25-mcp-server-generator-cli --interactive
```

This will guide you through:
1. Project naming
2. Author information
3. Tool definitions
4. Configuration options

### Command-Line Mode

For automation or when you have a tool definition file:

```bash
hitoshura25-mcp-server-generator-cli \
  --project-name my-mcp-tool \
  --description "Does something useful" \
  --author "Your Name" \
  --email "you@example.com" \
  --tools-file tools.json
```

### MCP Server Mode (For AI Agents)

Configure mcp-server-generator as an MCP server in Claude Desktop to let Claude generate MCP servers for you:

**Using uvx (recommended):**
```json
{
  "mcpServers": {
    "mcp-server-generator": {
      "command": "uvx",
      "args": ["hitoshura25-mcp-server-generator"]
    }
  }
}
```

**Using pipx/pip installation:**
```json
{
  "mcpServers": {
    "mcp-server-generator": {
      "command": "hitoshura25-mcp-server-generator"
    }
  }
}
```

**For detailed MCP configuration, see [MCP-USAGE.md](https://github.com/hitoshura25/mcp-server-generator/blob/main/MCP-USAGE.md)**

## MCP Server Tools

When used as an MCP server (in Claude Desktop or other MCP clients), mcp-server-generator provides powerful tools with **progressive disclosure** support - allowing AI agents to discover and use tools efficiently without loading all schemas upfront.

### Discovery Tools

**search_tools** - Find relevant tools by query
- Search by keywords, categories, or use cases
- Three detail levels for context efficiency:
  - `name`: Just tool names (most efficient)
  - `summary`: Names + descriptions + categories
  - `full`: Complete information including use cases
- Example: `search_tools(query="generate", detail_level="summary")`

**get_tool_info** - Get detailed information about a specific tool
- Two detail levels: `summary` or `full`
- Progressive disclosure for context efficiency
- Example: `get_tool_info(tool_name="generate_mcp_server", detail_level="full")`

### Generation Tools

**generate_mcp_server** - Generate complete MCP server projects
- Creates dual-mode architecture (MCP + CLI)
- Includes tests, documentation, and CI/CD workflows
- Production-ready scaffolding with best practices
- Supports async/await patterns

**generate_claude_command** - Create Claude Code command files
- Generates `.claude/commands/` directory structure
- Creates slash commands for guided MCP development
- Templates for common workflows: `mcp_generator`, `best_practices`, `implementation_helper`, `custom`
- Enables guided development experience

### Validation Tools

**validate_project_name** - Validate project names
- Check Python package compatibility
- Avoid Python keyword conflicts
- Ensure PyPI naming conventions

### Guidance Tools

**get_best_practices** - MCP development best practices
- Progressive disclosure strategies
- Context-efficient tool design
- Control flow optimization
- Security and privacy considerations
- State management patterns
- Testing strategies

**get_implementation_guide** - Step-by-step implementation guide
- Project setup and initialization
- Tool implementation patterns
- Testing strategies
- Deployment and publishing
- Claude Desktop integration

### Why Progressive Disclosure?

Progressive disclosure allows AI agents to:
- Discover tools without loading full schemas upfront
- Save context window space for actual work
- Scale to hundreds or thousands of tools
- Get exactly the level of detail needed

**Example workflow (MCP tool invocations):**
```
# 1. Search for relevant tools
search_tools(query="generate", detail_level="name")
# Returns: ["generate_mcp_server", "generate_claude_command"]

# 2. Get summary of specific tool
get_tool_info(tool_name="generate_mcp_server", detail_level="summary")
# Returns: name, description, category

# 3. Get full details when ready to use
get_tool_info(tool_name="generate_mcp_server", detail_level="full")
# Returns: complete information including use cases and parameters
```

## Package Prefix

To avoid namespace conflicts on PyPI, mcp-server-generator supports prefixing package names. This is **highly recommended** for unique package names.

### Prefix Modes

**AUTO (Recommended)**
- Automatically detects your GitHub username from git config
- Priority: `github.user` → remote URL → `user.name` (sanitized)
- Example: `my-tool` → `username-my-tool`

**Custom Prefix**
- Use your own prefix (organization name, brand, etc.)
- Example: `--prefix acme` → `acme-my-tool`

**NONE**
- No prefix applied (only if you have a truly unique name)
- Example: `unique-server-name` → `unique-server-name`

### Usage Examples

**Interactive Mode:**
```bash
hitoshura25-mcp-server-generator-cli --interactive
# You'll be prompted: "Prefix (default: AUTO): "
# - Press Enter for AUTO detection
# - Type "NONE" for no prefix
# - Type "acme" for custom prefix
```

**Command-Line:**
```bash
# AUTO mode (default)
hitoshura25-mcp-server-generator-cli --project-name calculator --prefix AUTO ...

# Custom prefix
hitoshura25-mcp-server-generator-cli --project-name calculator --prefix acme ...

# No prefix
hitoshura25-mcp-server-generator-cli --project-name unique-calculator --prefix NONE ...
```

**MCP Server Mode:**
```json
{
  "project_name": "calculator",
  "prefix": "AUTO",
  ...
}
```

### Generated Names

With prefix `username` and project `my-tool`:
- **PyPI Package**: `username-my-tool` (install with `pip install username-my-tool`)
- **Python Import**: `username_my_tool` (use in code as `import username_my_tool`)
- **CLI Command**: `username-my-tool` (run as `username-my-tool --help`)
- **MCP Command**: `mcp-username-my-tool` (use in config)

**For detailed MCP configuration, see [MCP-USAGE.md](https://github.com/hitoshura25/mcp-server-generator/blob/main/MCP-USAGE.md)**

│     mcp-server-generator            │
├─────────────────────────────────────┤
│                                     │
│  ┌──────────┐      ┌──────────┐     │
│  │ MCP Mode │      │ CLI Mode │     │
│  └────┬─────┘      └────┬─────┘     │
│       │                 │           │
│       └────────┬────────┘           │
│                │                    │
│         ┌──────▼───────┐            │
│         │ generator.py │            │
│         │ (Core Logic) │            │
│         └──────────────┘            │
│                                     │
└─────────────────────────────────────┘
```

Both modes use the same core generator logic, ensuring consistency.
