# MCP Cookie Cutter

A powerful CLI tool and cookiecutter template for creating Model Context Protocol (MCP) servers. Get a fully-configured MCP server in seconds with a single command, then customize it for your API.

## Features

- 🎯 **CLI Tool**: One command to generate your MCP server - `pip install mcp-cookie-cutter && mcp-cookie-cutter`
- 🚀 **Quick Start**: Generate a working MCP server in seconds
- 🐍 **Python with FastMCP**: Modern Python-based MCP servers with FastMCP framework
- 🔧 **OpenAPI Auto-Generation**: Automatically generates tools from OpenAPI/Swagger specs
- 🌐 **Local & Remote**: Support for STDIO (local) and Streamable HTTP (remote) transports
- 🔐 **Authentication**: Built-in templates for OAuth 2.1 and API key authentication
- 📦 **Full-Featured**: Auto-generated tools, prompts, and Pydantic models
- 📝 **Easy Customization**: Clear examples and guides for adding your API tools
- ⚡ **Modern Tooling**: Uses uv for package management and uvicorn for production
- ✅ **Best Practices**: Follows MCP specification and security guidelines

## What You Get

- Complete MCP server project structure
- **Intelligent OpenAPI parsing** - See available API operations during generation
- Example tool implementations (GET and POST)
- Comprehensive CUSTOMIZATION.md guide
- Authentication templates
- Development environment setup
- Claude Desktop integration instructions

## Prerequisites

- Python 3.10+ (required)

## Installation & Usage

### 🎯 Option 1: CLI Tool (Recommended - Easiest!)

The fastest way to get started:

```bash
# Install the CLI tool
pip install mcp-cookie-cutter

# Generate your MCP server
mcp-cookie-cutter

# Or with specific options
mcp-cookie-cutter --no-input project_name="My API Server"
```

**That's it!** The CLI bundles everything you need.

### 🔧 Option 2: Use with Cookiecutter

If you prefer using cookiecutter directly:

```bash
# Install cookiecutter first
pip install cookiecutter

# Use the template from GitHub
cookiecutter gh:maheshmahadevan/mcp-cookie-cutter
```

### Dependency Details

All dependencies are automatically installed with the CLI tool. If using cookiecutter directly:

- **cookiecutter** (required) - Template generation engine
- **pyyaml** (optional) - For parsing YAML OpenAPI specs
- **requests** (optional) - For fetching OpenAPI specs from URLs
- **openapi-pydantic** (optional) - For validating and parsing OpenAPI schemas with type safety
- **datamodel-code-generator** (optional) - For generating Pydantic models

Without the optional dependencies, you can still generate MCP servers, but OpenAPI spec parsing and tool suggestions will not be available.

## Quick Start

### Step 1: Install and Run

**Using CLI (recommended):**
```bash
pip install mcp-cookie-cutter
mcp-cookie-cutter
```

**Or using cookiecutter:**
```bash
cookiecutter gh:maheshmahadevan/mcp-cookie-cutter
```

### Step 2: Answer the Prompts

You'll be asked to configure:

- **Project name**: Name of your MCP server
- **Project description**: Brief description
- **Author information**: Your name and email
- **OpenAPI spec path**: *(Optional)* Path or URL to your OpenAPI/Swagger spec
- **Deployment type**: Local (STDIO) or Remote (Streamable HTTP)
- **Server port**: Port for remote deployment (default: 8000)
- **Authentication**: None, API key, or OAuth 2.1
- **License**: Choose from MIT, Apache-2.0, BSD-3-Clause, GPL-3.0, or Proprietary

### Step 3: Customize Your Tools

The generated server includes example tools. Follow the CUSTOMIZATION.md guide to add your API endpoints.

### Step 4: Run Your Server

Follow the setup instructions displayed after generation, or see the generated README.md.

### Features

- **OpenAPI Integration**: Auto-generates tools, prompts, and Pydantic models from OpenAPI specs
- **FastMCP Framework**: Modern Python MCP framework with decorator-based tool definitions
- **Transport Support**:
  - **Local (STDIO)**: For Claude Desktop and local clients
  - **Remote (Streamable HTTP)**: Production-grade HTTP server with uvicorn
- **Authentication**:
  - **None**: Open access (local development only)
  - **API Key**: Bearer token authentication
  - **OAuth 2.1**: Standards-compliant OAuth with PKCE support
- **MCP Features**:
  - **Tools**: Auto-generated from OpenAPI operations (individual files per tool)
  - **Prompts**: Auto-generated helpful prompts from API operations
  - **Models**: Pydantic models from OpenAPI schemas
  - **Logging**: Proper stderr logging (STDIO-safe)

## OpenAPI/Swagger Integration

The template includes intelligent OpenAPI parsing that:

1. **Loads your OpenAPI/Swagger specification** (from file or URL)
2. **Validates the spec** using openapi-pydantic (if installed)
3. **Extracts all available endpoints** (GET, POST, PUT, DELETE, PATCH)
4. **Displays operation details** during generation

### Supported OpenAPI Formats

- OpenAPI 3.0/3.1 (JSON or YAML)
- Swagger 2.0 (JSON or YAML)

### Example OpenAPI Flow

```bash
# Provide your OpenAPI spec path when prompted
openapi_spec_path: https://petstore.swagger.io/v2/swagger.json

# The hook will scan and display:
✨ Found 20 available API operations:
----------------------------------------------------------------------
 1. POST   /pet                           - addPet
     Add a new pet to the store
 2. GET    /pet/{petId}                   - getPetById
     Find pet by ID
...
----------------------------------------------------------------------

💡 You can implement these as MCP tools in your generated server.
```

See [OPENAPI_PARSING.md](OPENAPI_PARSING.md) for detailed documentation on OpenAPI parsing.

## Configuration Examples

### Local Server with No Auth

```
deployment_type: local
auth_mechanism: none
openapi_spec_path: https://petstore3.swagger.io/api/v3/openapi.json
```

Result: STDIO-based server for Claude Desktop with auto-generated tools

### Remote Server with API Keys

```
deployment_type: remote
server_port: 9090
auth_mechanism: api_key
openapi_spec_path: https://petstore3.swagger.io/api/v3/openapi.json
```

Result: Streamable HTTP server with API key authentication and auto-generated tools

### Remote Server with OAuth

```
deployment_type: remote
server_port: 8000
auth_mechanism: oauth2
openapi_spec_path: https://api.github.com/openapi.json
```

Result: Streamable HTTP server with OAuth 2.1 authentication

## Best Practices

The generated servers follow MCP best practices:

1. **Security**:
   - OAuth 2.1 recommended for public clients
   - API keys for internal services
   - Proper user consent flows
   - Environment-based credential management

2. **Transport**:
   - STDIO for local deployments (no network exposure)
   - SSE for remote deployments (stateful connections)
   - Proper logging to stderr (never stdout)

3. **Error Handling**:
   - Comprehensive error messages
   - Input validation
   - Graceful degradation

4. **Code Quality**:
   - Type hints (Python) / TypeScript types
   - Linting and formatting configuration
   - Testing setup included

## Development

### Customizing the Template

The template uses Jinja2 templating. Key files:

- `cookiecutter.json`: Configuration options
- `hooks/pre_gen_project.py`: Pre-generation validation and OpenAPI scanning
- `hooks/post_gen_project.py`: Post-generation setup and cleanup
- `{{cookiecutter.project_slug}}/`: Template files with Jinja2 syntax

### Testing Your Template

```bash
# Generate a test project
cookiecutter . --no-input

# Or with specific values
cookiecutter . --no-input deployment_type=local auth_mechanism=none

# Test with OpenAPI spec
cookiecutter . --no-input \
  openapi_spec_path="https://petstore3.swagger.io/api/v3/openapi.json" \
  deployment_type="remote" \
  server_port="9090"
```

## Testing Resources

Test your MCP Cookie Cutter template with these verified APIs that have OpenAPI 3.0 specifications:

### 1. **Swagger Petstore** ⭐ Recommended for Testing
- **OpenAPI Spec**: https://petstore3.swagger.io/api/v3/openapi.json
- **Base URL**: https://petstore3.swagger.io/api/v3
- **Auth**: None required
- **Resources**: Pets, Store, Users
- **Why**: Gold standard for API testing, fully functional, no auth needed

### 2. **JSONPlaceholder** - Simple & Free
- **OpenAPI Spec**: https://gist.githubusercontent.com/oshevtsov/7d17f88f74730ce9c95b6d7bb3e03c3d/raw/jsonplaceholder-openapi-3.0.yaml
