### Description (declared)

# WAL MCP Server

MCP (Model Context Protocol) server for RTL waveform analysis using WAL (Waveform Analysis Language).

## Supported Waveform Formats

- VCD (Value Change Dump)
- FST (Fast Signal Trace)
- Any other formats supported by WAL

## Installation and Usage

```bash
pip install wal-mcp
```

Add to your MCP client configuration:

```json
{
  "mcpServers": {
    "wal-mcp": {
      "type": "stdio",
      "command": "wal-mcp-server",
      "args": []
    }
  }
}
```

For WAL expression syntax and advanced examples, see the [WAL documentation](https://wal-lang.org/documentation/usage).

This package also comes with script to install a skill and sufficient reference material to teach an AI agent how to write WAL.
This allows you to use natural language to analyze waveforms.

To install the skill into `.claude/skills/` your current directory run:

```sh
wal-mcp-install-skills
```

Or pass a filepath to the script to install elsewhere.

Alternatively, if you are using the Github CLI application you can install the skill using that.

```sh
gh install skill ktbarrett/wal-mcp
```

## Development

To set up a development environment, install the `dev` group and the current package.
This is easiest done with `uv`.

```bash
uv sync
```

There are also pre-commit hooks which will run lints whenever you make a commit.
`prek` is the recommended pre-commit hook runner.

First install `prek` if you already haven't.

```
uv tool install prek
```

Then install the git hooks.

```
prek install
```

## Testing

`pytest` is used for testing.
Run the following to run all the tests and collect coverage.

```bash
pytest
```

You can better visualize the coverage by using a coverage report format such as `html`.

```
coverage html
```
