# OneTool

> MCP server exposing a single `run` tool for LLM code execution.

OneTool reduces tool-definition context overhead by exposing tools as Python APIs.

## Quick Start

```bash
uv tool install 'onetool-mcp[all]'
onetool init --config ~/.onetool
onetool --config ~/.onetool/onetool.yaml --secrets ~/.onetool/secrets.yaml
```

## Invocation

```python
>>> brave.search(query="AI news")
```

## Adding Tools

Create a new extension module (example path):

```python
# src/mytool.py
from ot.decorators import tool

pack = "mytool"

@tool
def hello(*, name: str) -> str:
    """Return a greeting."""
    return f"Hello, {name}!"
```

Then include it in your config `tools_dir` glob.
