Agentic HIL MCP Server

Your AI agent writes the firmware, flashes it to the board on your desk, drives UART and CAN against it, reads back what the hardware actually did, and fixes what it got wrong; the run on the real board is what decides whether the work is done, and you review the pull request with that run's evidence in it. It runs locally over stdio via the published package.

People who work with embedded, hardware in the loop and openocd and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Agentic HIL

Claude Code

claude mcp add agentic-hil-agentic-hil -- uvx agentic-hil

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "agentic-hil-agentic-hil": {
      "command": "uvx",
      "args": [
        "agentic-hil"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
