CrewAI is a Python framework for orchestrating multi-agent workflows with autonomous teams (crews) and event-driven flows. The Steel integration exposes a Steel browser as a CrewAI tool, so your crew can search, navigate, fill forms, extract data, and validate results across collaborating agents.

You can mix autonomy with precise control, share memory across steps, return structured outputs, and add human-in-the-loop checkpoints for sensitive actions.

### Requirements

*   **Steel API Key**: Active Steel subscription
*   **LLM API key**: OpenAI or any CrewAI-supported provider
*   **Python**: 3.10–3.13

### Connect Steel to CrewAI

Expose Steel as a CrewAI `BaseTool` your agents can call:

```python Python -wc
import os
from crewai.tools import BaseTool
from steel import Steel

class SteelScrapeTool(BaseTool):
    name: str = "Steel web scrape"
    description: str = "Scrape webpages with Steel and return markdown"

    def __init__(self):
        super().__init__()
        self._steel = Steel(steel_api_key=os.environ["STEEL_API_KEY"])

    def _run(self, url: str):
        return self._steel.scrape(url=url, format=["markdown"])
```

### FAQ

### Do I need to change my existing CrewAI code to use Steel?

No — Steel plugs in as a regular CrewAI tool. Define a `BaseTool` subclass whose `_run` method calls Steel, hand it to your agents, and your crews, flows, and memory setup stay untouched.

### How do I connect CrewAI to Steel?

Expose Steel as a CrewAI `BaseTool`: instantiate the Steel client in `__init__` and call it from `_run`. The page's example tool scrapes a URL with `self._steel.scrape(url=url, format=["markdown"])` and returns markdown to the agent.

### Does CrewAI work with Steel's proxies, stealth mode, and CAPTCHA solving?

Yes — when your tool creates Steel sessions you can enable these at session creation (e.g. `use_proxy`, `solve_captcha`, `stealth_config`). They're Steel-side options, so CrewAI's orchestration doesn't change.

### Do I need a full browser session, or is scraping enough for a crew?

For read-only research, the page's tool uses Steel's `scrape` API to return page markdown — no session management needed. For interactive flows (forms, clicks, multi-step navigation), create a Steel session inside the tool instead.
