# MCP ESPTool Server

FastMCP server providing AI-powered ESP32/ESP8266 development workflows through natural language interfaces.

## Features

- **Chip Control**: Advanced ESP device detection, connection, and control
- **Flash Operations**: Comprehensive flash memory management with safety features
- **Security Management**: ESP security features including secure boot and flash encryption
- **Production Tools**: Factory programming and batch operations
- **Middleware System**: Universal CLI tool integration with bidirectional MCP communication
- **ESP-IDF Integration**: Host application support for hardware-free development

## Quick Start

### Installation

```bash
# Install with uvx (recommended)
uvx mcp-esptool-server

# Or install in project
uv add mcp-esptool-server
```

### Claude Code Integration

```bash
# Add to Claude Code
claude mcp add mcp-esptool-server "uvx mcp-esptool-server"
```

### Development Setup

```bash
# Clone and setup
git clone <repository>
cd mcp-esptool
make dev

# Run development server
make run-debug

# Run tests
make test
```

## Architecture

The server implements a component-based architecture with middleware for CLI tool integration:

- **Components**: Specialized modules for different ESP development workflows
- **Middleware**: Universal pattern for intercepting and redirecting CLI tool output to MCP context
- **Configuration**: Environment-based configuration with auto-detection
- **Production Ready**: Docker support with development and production modes

## Components

- `ChipControl`: Device detection, connection management, reset operations
- `FlashManager`: Flash operations with verification and backup
- `PartitionManager`: Partition table management and OTA support
- `SecurityManager`: Security features and eFuse management
- `FirmwareBuilder`: ESP-IDF integration and binary operations
- `OTAManager`: Over-the-air update workflows
- `ProductionTools`: Factory programming and quality control
- `Diagnostics`: Memory dumps and performance profiling

## Configuration

Configure via environment variables or `.env` file:

```bash
ESPTOOL_PATH=esptool
ESP_DEFAULT_BAUD_RATE=460800
ESP_IDF_PATH=/path/to/esp-idf
MCP_ENABLE_PROGRESS=true
PRODUCTION_MODE=false
```

## Docker

```bash
# Development with hot reload
make docker-up

# Production deployment
DOCKER_TARGET=production make docker-up
```
