Hey HN, we are Richard and Byungkyu from Maton.

Two years ago, OpenAI launched ChatGPT Plugins, and we thought it was an exciting idea - give AI access to external apps and allow them to perform tasks beyond just conversation.

Then, for some reason, OpenAI decided to pivot and deprecate it in favor of GPTs.

That's why we're building Maton (https://toolkit.maton.ai). We're bringing back what ChatGPT Plugins was meant to be - making it simple to connect AI to any app.

In just a few lines of code, you can give your AI access to hundreds of pre-built API actions for popular SaaS tools like HubSpot, Notion, Slack, and more.

    import {MatonAgentToolkit} from '@maton/agent-toolkit/openai';
    
    const toolkit = new MatonAgentToolkit({
        app: 'salesforce',
        actions: ['all'],
    })
    const completion = await openai.chat.completions.create({
        model: 'gpt-4o-mini',
        tools: toolkit.getTools(),
        messages: [...]
    })

We also take care of authentication for you. The toolkit comes with two default tools: `start_connection` and `check_connection`. If the user account isn't connected, `start_connection` returns a link to our auth UI where the user can connect their accounts via OAuth or API key. We manage the credentials and refresh them when necessary.

Last but not least, if you're not using OpenAI, we support AI SDK, LangChain, and more and provide MCP servers that you can use in Claude for Desktop, Cursor, and Continue.
