Verdict

Pick ESP-MCP if you prefer its approach (centralize esp-idf/esp32 commands and drive embedded builds, flashing, and tests via llm-driven mcp tools).

Pick Serena if you prefer the more popular, battle-tested option, and you need the broadest set of tools.

      "command": "<path_to_uv_or_python_executable>",
      "args": [
        "--directory",
        "<path_to_cloned_esp-mcp_repository>",
        "run",
        "main.py"
      ],
      "env": {

{
  "mcpServers": {
    "serena": {
      "command": "uvx",
      "args": [
        "--from",
