### Description (declared)

# openinverter-mcp

MCP server for [openinverter](https://openinverter.org/) / EV-CAN work: inspect openinverter
parameter databases, decode and encode CAN frames via DBC files, and analyze recorded CAN
logs — from Claude Code, Claude Desktop, or any MCP client.

Built for DIY EV builders (Leaf/Tesla drive units, stm32-sine firmware). **No CAN hardware
required**: the DBC, log, and param-DB lanes are fully usable standalone on files. Live
device access exists but is deliberately locked behind a feature flag (see Safety).

## Install

Requires Python 3.10+.

```sh
pip install openinverter-mcp        # once published; from a clone:
git clone <this repo> && cd openinverter-mcp
uv sync                             # or: pip install -e .
```

## Register with Claude Code

From a clone (project-scoped `.mcp.json` in this repo already does this):

```sh
claude mcp add openinverter -- uv run --directory C:/path/to/openinverter-mcp openinverter-mcp
```

Once on PyPI, no clone needed:

```sh
claude mcp add openinverter -- uvx openinverter-mcp
```

Then in a session: "load assets/sample.dbc and decode 0x156 701C2D2ED40D4A00".

## Tools

Handles (`dbc:1`, `log:1`, `paramdb:1`) are returned by the load tools; every tool that
takes a handle also accepts a file path directly.

| Tool | What it does |
|---|---|
| `server_info` | Version, device-lane status, loaded handles. Smoke test. |
| `dbc_load` | Load a DBC file → handle + message/node summary. |
| `dbc_info` | List messages (with `search` over message/signal names) or full signal detail for one message. |
| `decode_frame` | One raw frame (id + hex data) → named signal values. |
| `encode_message` | Signal values → frame bytes (hex + candump form), range-checked. |
| `log_open` | Open a recorded log: candump `.log`, Vector `.blf`, python-can `.csv`, `.asc`, `.trc`. |
| `log_stats` | Bus overview: per-id counts, rates (Hz), time span, DLC profile. |
| `log_decode` | Decode a log through a DBC; id filter + pagination; unknown id…
