Overview

What is Esp Mcp?

Esp Mcp is a Model Context Protocol (MCP) server that consolidates ESP-IDF and related project commands into a single interface, simplifying embedded development through LLM communication. It is currently a Proof of Concept (PoC) tailored for ESP-IDF workflows.

How to use Esp Mcp?

Clone the repository and configure it in your MCP-supporting chatbot using a JSON snippet that specifies the command (path to uv or Python), arguments, and optional IDF_PATH environment variable. Once running, you can ask your chatbot to execute ESP-IDF commands like installing dependencies, creating projects, setting targets, building, flashing, and running pytest tests.

Key features of Esp Mcp

  • Install ESP-IDF dependencies and toolchain via install.sh.
  • Create new ESP-IDF projects.
  • Set target chip for projects (e.g., esp32, esp32c3, esp32s3).
  • Build projects with incremental build support.
  • List available serial ports for ESP devices.
  • Flash built firmware to connected devices.
  • Run pytest tests with pytest-embedded support.
  • Flexible per-project ESP-IDF path management.
  • SDK config management using custom sdkconfig_defaults files.
  • Build time tracking and optional port specification for flashing.

Use cases of Esp Mcp

  • Set up a new ESP-IDF development environment from scratch.
  • Create, build, and flash ESP32 firmware projects using natural language.
  • Run automated tests for multiple ESP targets across different projects.
  • Manage multiple ESP-IDF versions per project without manual environment switching.
  • Debug build issues with experimental automatic log-based fix suggestions.

Frequently asked questions

1

What is Esp Mcp and what does it do?

It is an MCP server that provides a set of tools to interact with ESP-IDF projects, allowing LLMs or chatbots to perform development tasks like installing dependencies, building, flashing, and testing.

2

How do I install Esp Mcp?

Clone the repository from GitHub (`git clone git@github.com:horw/esp-mcp.git`) and configure it in your chatbot using a JSON snippet that includes the command path, arguments, and optionally the `IDF_PATH` environment variable pointing to your ESP-IDF installation.

3

Does Esp Mcp require ESP-IDF to be installed?

Yes. ESP-IDF must be installed on your system. You can specify its location via the `IDF_PATH` environment variable or by passing an `idf_path` parameter directly to each tool call, which supports multiple ESP-IDF versions.

4

What tools/commands does Esp Mcp provide?

It provides eight core tools: `run_esp_idf_install`, `create_esp_project`, `setup_project_esp_target`, `build_esp_project`, `list_esp_serial_ports`, `flash_esp_project`, and `run_pytest`.

5

Is Esp Mcp production-ready?

No. It is currently a Proof of Concept (PoC) for ESP-IDF workflows, with experimental features and planned expansion into broader embedded device interaction.
