# Using Composio With Cloudflare Worker AI

> Integrate Composio with Cloudflare Worker AI to let them seamlessly interact with external apps

## Star A Repository on Github

In this example, we will use Cloudflare Worker AI to star a repository on Github using Composio Tools

<Steps>
  <Step title="Install Packages">
    ```bash JavaScript
    npm install composio-core -g wrangler fs
    ```
  </Step>

  <Step title="Setup wrangler in wrangler.toml file">
    ```toml wrangler.toml
    name = "github-agent"
    main = "worker.js"
    compatibility_date = "2024-09-23"
    compatibility_flags = ["nodejs_compat"]

    [vars]
    COMPOSIO_API_KEY = "<your-composio-api-key>"

    [ai]
    binding = "AI"
    ```
  </Step>

  <Step title="Import Libraries & Initialize Hono">
    ```javascript worker.js
    import { Hono } from 'hono';
    import { CloudflareToolSet } from "composio-core"

    const app = new Hono();
    ```
  </Step>

  <Step title="Create an endpoint & get GitHub Tools">
    You can get all the tools for a given app as shown below, but you can get **specific actions** and filter actions using **usecase** & **tags**. Learn more [here](../../patterns/tools/use-tools/use-specific-actions)

    ```javascript worker.js
    app.post('/', async (c) => {
        const toolset = new CloudflareToolSet();

        try {
            const tools = await toolset.getTools({ apps: ['github'] });
            const instruction = 'Star the repository "composiohq/composio"';    

            let messages = [
                { role: 'system', content: '' },
                { role: 'user', content: instruction },
            ];

            const config = {
                model: '@hf/nousresearch/hermes-2-pro-mistral-7b',
            };

            const toolCallResp = await c.env.AI.run(config.model, {
                messages,
                tools,
            });

            await toolset.handleToolCall(toolCallResp, entity.id);
            return c.json({ messages: "Your issue has been created" });
        } catch (err) {
            console.log(err);
            return c.text('Something went wrong', 500);
        }

        export default app;
    });
    ```
  </Step>

  <Step title="Start the Worker">
    ```bash CLI
    wrangler dev
    ```
  </Step>
