Quickstart

Get OneTool running in under 2 minutes.

1. Install uv

OneTool requires uv - a fast Python package manager.

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

2. Install OneTool

uv tool install onetool-mcp

3. Initialize

onetool init

This creates configuration files in ~/.onetool/config/:

  • onetool.yaml - Global settings
  • secrets.yaml - API keys (gitignored)

4. Set Up Secrets

Edit ~/.onetool/config/secrets.yaml to add your API keys:

# Brave Search API

5. Validate

onetool init validate

This checks your configuration is correct.

6. Connect to Claude Code

claude mcp add onetool onetool

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

{
  "mcpServers": {
    "onetool": {
      "command": "onetool"
    }
  }
}

7. Verify Connection

Start Claude Code and run /mcp. You should see OneTool listed as a connected MCP server.

8. Use It

Try a simple health check:

__ot ot.health()

Or use a prompt like this to ask the agent to help you use OneTool. Note: the ubad= parameter is intentional to demonstrate how OneTool handles errors.

Issue each command, one at a time.
Before each command explain what you are doing so it is easy for the new OneTool user to follow what you did and why. Use 🧿 to highlight these explanations.
After each command output ✅ and the results of the call or ❌ and the error or issue. Provide a readable snippet of the results.
Use OneTool ot.help() with info="full" to understand how best to use OneTool tools.
Finally, list all OneTool commands used.

Commands:
__ot ot.health()
__ot ot.help()
__ot ot.help(q="web.fetch", i="full")
__ot web.fetch(ubad="https://onetool.beycom.online/")
__ot web.fetch(u="https://onetool.beycom.online/")
__ot $pkg

That's it.
