## The Problem

Each MCP server consumes **3K-30K tokens per request**. Connect 5 servers and you've burned 55K tokens before the conversation starts. Connect 10+ and you're at 100K tokens.

The math is brutal: Claude Opus 4.5 at $5/M input tokens, 20 days × 10 conversations × 10 messages × 3K tokens = **$30/month per MCP server** - even if you never use the tools.

And then there's **context rot** - your AI literally gets dumber as you add more tools ([Chroma Research, 2025](https://research.trychroma.com/context-rot)).

## The Solution

OneTool is **one MCP server** that exposes tools as a Python API. Instead of reading tool definitions, your agent writes code:

```python
>>> brave.search(query="react docs 2026")
```

Configure one MCP server. Use unlimited tools.

> "Agents scale better by writing code to call tools instead. Thi…
