## 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
__ot brave.search(query="react docs 2026")
```

Configure one MCP server. Use unlimited tools.

> "Agents scale better by writing code to call tools instead. This reduces the token usage from 150,000 tokens to 2,000 tokens...a cost saving of 98.7%"
>
> — [Anthropic Engineering](https://www.anthropic.com/engineering/code-execution-with-mcp)

**96% fewer tokens. 24× lower cost. No context rot.**

## Install

Requires [uv](https://docs.astral.sh/uv/):

```bash
uv tool install onetool-mcp
onetool init
```

Add to Claude Code:

```bash
claude mcp add onetool onetool
```

Or manually add to `~/.claude/mcp.json`:

```json
{
  "mcpServers": {
    "onetool": {
      "command": "onetool"
    }
  }
}
```

That's it. All 100+ tools work out of the box.

Verify: `onetool init validate`

## MCP Server Proxy

Wrap any existing MCP server and call it explicitly - without the tool tax:

```yaml
# .onetool/onetool.yaml
mcp_servers:
  chrome-devtools:
    command: npx
    args: ["-y", "@anthropic-ai/chrome-devtools-mcp@latest"]
  github:
    command: npx
    args: ["-y", "@anthropic-ai/github-mcp-server@latest"]
```

```python
__ot mcp.call(server="github", tool="get_file_contents", arguments={"path": "README.md"})
```

[📖 Configuration guide](https://onetool.beycom.online/learn/configuration/#external-mcp-servers)

---

## Extending

Drop a Python file, get a pack. No registration, no config:

```python
# .onetool/tools/wiki.py
pack = "wiki"

def summary(*, title: str) -> str:
    """Get Wikipedia article summary."""
    import httpx
    url = f"https://en.wikipedia.org/api/rest_v1/page/summary/{title}"
    return httpx.get(url).json().get("extract", "Not found")
```

```python
__ot wiki.summary(title="Python_(programming_language)")
```
