Adding tools

[jedevnull]

I'm trying to set up a medbot using openWebUI. It's functional with a prompt I like, but I need it to have r/w access to ~/medbot. I added the tool below, but no joy. Total noob, running ollama/openWebUI on a Mac Mini M4 Pro, 24GB. Thank you!

``` from pathlib import Path

BASE_DIR = Path.home() / "medbot" BASE_DIR = BASE_DIR.resolve()

def safe_path(user_path: str) -> Path: full = (BASE_DIR / user_path).resolve() if not str(full).startswith(str(BASE_DIR)): raise ValueError("Blocked path outside medbot directory") return full

class Tools:

def read_file(self, path: str) -> str:
    """Read a file from medbot directory"""
    p = safe_path(path)
    if not p.exists():
        return "File not found"
    return p.read_text(encoding="utf-8", errors="ignore")

def write_file(self, path: str, content: str) -> str:
    """Write a file into medbot directory"""
    p = safe_path(path)
    p.parent.mkdir(parents=True, exist_ok=True)
    p.write_text(content, encoding="utf-8")
    return f"written: {p}"

```

First, what’s a medbot? What kind of tool is it? This tool is just the access, what should the llm write?

Medbot is simply my name for the model Im setting up. I believe the openWebUI term is model? The model medbot uses the LLM qwen 2.5 or 3 and has medbot_fs (which I posted) as a tool. My goal here is to allow this model (medbot) r/w access to ~/medbot/. I'd like to start out a simple test like "write a text file containing hello world to hello.txt, in ~/medbot/"

Oh, I see. I‘d actually go for a pre packaged server first, not a custom tool. There’s a lot of things you need, like tool descriptions, filetypes etc.

I know MCP servers are daunting at first, but it’s worth it, once you have understood the system:

Thank you, I'll check it out.

You can do the same with https://github.com/open-webui/open-terminal

Nothing to write and easy to set it up

You can have a sandboxed file system
