Types

You can generate types for the plug tools by using the cli.

npx mcplug types <PLUG_ID>

This will generate a <PLUG_NAME>.d.ts file in the src or root directory of your project. You can then use the type in your code by passing it as generic of the mcplug function.

const tools = await mcplug<MCPLUG_YOUR_PLUG_NAME>({
  token: PLUG_TOKEN,
  id: PLUG_ID
});

const result = await generateText({
  model: openai("gpt-4o"),
  messages: [
    {
      role: "user",
      content: "What is the weather in Paris?"
    }
  ],
  // Necessary to let the LLM use the tools in a loop if needed and generate a response
  maxSteps: 10,
  tools
});

After that, the toolCalls or toolResults properties of the result will be typed and you will be able to use them safely in your code.

Specifying the folder

You can specify the folder of the generated types by using the --folder flag.

npx mcplug types <PLUG_ID> --output src/types
