### Description (declared)

# ESP-Workspace MCP

A full autonomous embedded firmware workspace server — the MCP (Model Context Protocol) infrastructure layer for AI agents working with ESP-IDF projects.

## What it does

ESP-Workspace MCP turns an AI coding assistant into an autonomous firmware engineer. It provides tools for:

- **Filesystem operations** — read, write, list, glob with path sandboxing
- **Shell execution** — run commands with timeout, background jobs, output capture
- **ESP-IDF build system** — build, flash, clean, reconfigure via `eim run` with `WISH_PRODUCT` support
- **Security** — Bearer token auth, path traversal prevention, configurable filesystem roots

## Quick Start

### Prerequisites

- Python 3.10+
- [Espressif Install Manager (`eim`](https://github.com/espressif/esp-idf-installer) — handles ESP-IDF installation and environment setup

### Installation

```bash
pip install esp-workspace-mcp
```

Or from source:

```bash
git clone https://github.com/AIRcableLLC/esp-workspace-mcp.git
cd esp-workspace-mcp
python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
```

### Configuration

Create a `.env` file:

```env
MCP_API_TOKEN=your-secret-token-here
MCP_HOST=0.0.0.0
MCP_PORT=8765
MCP_ALLOWED_ROOTS=/home/user/projects
MCP_WISH_PRODUCT=TargetS3
MCP_EIM_PATH=eim
```

Or set environment variables directly.

### Run the server

```bash
# SSE mode (default, for network access)
python run_server.py

# Stdio mode (for local MCP clients)
python run_server.py --stdio
```

The server exposes:
- `GET /sse` — SSE connection endpoint (requires Bearer token)
- `POST /messages` — MCP message endpoint
- `GET /health` — health check (no auth required)

## MCP Tools
