AI SDK - AI agent tools

The @tiptap-pro/ai-toolkit-ai-sdk package provides tool definitions you can add to your AI agent built with the AI SDK by Vercel.

The tool calls generated by the model can then be executed using the executeTool method.

Example usage

Install the package.

npm install @tiptap-pro/ai-toolkit-ai-sdk

Supply the tool definitions to the tools parameter of the generateText or streamText functions.

import { openai } from '@ai-sdk/openai'
import { streamText } from 'ai'
import { toolDefinitions } from '@tiptap-pro/ai-toolkit-ai-sdk'

const result = streamText({
  model: openai('gpt-5'),
  tools: toolDefinitions(),
})

Combine the tool definitions with your custom tools.

import { openai } from '@ai-sdk/openai'
import { streamText, tool } from 'ai'
import { toolDefinitions } from '@tiptap-pro/ai-toolkit-ai-sdk'
import { z } from 'zod'

const result = streamText({
  model: openai('gpt-5'),
  tools: {
    // Tool definitions from the AI Toolkit
    ...toolDefinitions(),
    // Custom weather tool
    weather: tool({
      description: 'Get the weather in a location',
      inputSchema: z.object({
        location: z.string(),
      }),
      execute: async () => ({
        temperature: 72,
      }),
    }),
  },
})
