Intro

Agentic is a standard library of AI functions / tools which are optimized for both normal TS-usage as well as LLM-based usage. Agentic works with all of the major TS AI SDKs (Vercel AI SDK, Mastra, LangChain, LlamaIndex, OpenAI SDK, MCP, etc).

Agentic clients like WeatherClient can be used as normal TS classes:

import { WeatherClient } from '@agentic/stdlib'

// Requires `process.env.WEATHER_API_KEY` (free from weatherapi.com)
const weather = new WeatherClient()

const result = await weather.getCurrentWeather({
  q: 'San Francisco'
})
console.log(result)

Or you can use these clients as LLM-based tools. Here's an example using Vercel's AI SDK:

// sdk-specific imports
import { openai } from '@ai-sdk/openai'
import { generateText } from 'ai'
import { createAISDKTools } from '@agentic/ai-sdk'

// sdk-agnostic imports
import { WeatherClient } from '@agentic/stdlib'

const weather = new WeatherClient()

const result = await generateText({
  model: openai('gpt-4o-mini'),
  // this is the key line which uses the `@agentic/ai-sdk` adapter
  tools: createAISDKTools(weather),
  toolChoice: 'required',
  prompt: 'What is the weather in San Francisco?'
})

console.log(result.toolResults[0])

You can use our standard library of thoroughly tested AI functions with your favorite AI SDK – without having to write any glue code!

Using Multiple Tools

All adapters (like createAISDKTools) accept a very flexible var args of AIFunctionLike parameters, so you can pass as many tools as you'd like.

They also expose a .functions property which is an AIFunctionSet. This combination makes it really easy to mix & match different tools together.

import { SerperClient, WikipediaClient, FirecrawlClient } from '@agentic/stdlib'
import { createAIFunction } from '@agentic/core'
import { z } from 'zod'

const googleSearch = new SerperClient()
const wikipedia = new WikipediaClient()
const firecrawl = new FirecrawlClient()

const result = await generateText({
  model: openai('gpt-4o-mini'),
  // This example uses tools from 4 different sources. You can pass as many
  // AIFunctionLike objects as you want.
  tools: createAISDKTools(
    googleSearch,
    wikipedia,
    // Pick a single function from the firecrawl client's set of AI functions
    firecrawl.functions.pick('firecrawl_search'),
    // Create a custom AI function (based off of Anthropic's think tool: https://www.anthropic.com/engineering/claude-think-tool)
    createAIFunction({
      name: 'think',
      description: `Use this tool to think about something. It will not obtain new information or change the database, but just append the thought to the log. Use it when complex reasoning or some cache memory is needed.`,
      inputSchema: z.object({
        thought: z.string().describe('A thought to think about.')
      }),
      execute: ({ thought }) => thought
    })
  ),
  prompt:
    'What year did Jurassic Park the movie come out, and what else happened that year?'
})

An AIFunctionLike can be any agentic client instance, a single AIFunction selected from the client's .functions property (which holds an AIFunctionSet of available AI functions), or an AI function created manually via createAIFunction.

AIFunctionLike and AIFunctionSet are implementation details that you likely won't have to touch directly, but they're important because of their flexibility.

Features

• ✅ All tools are thoroughly tested in production
• ✅ Tools work across all leading TS AI SDKs
• ✅ Tools are hand-coded and extremely minimal
• ✅ Tools have both a good manual DX and LLM DX via the @aiFunction decorator
• ✅ Tools use native fetch
• ✅ Tools use ky to wrap fetch, so HTTP options, throttling, retries, etc are easy to customize
• ✅ Supports tools from any MCP server (createMcpTools(...))
• ✅ Generate new Agentic tool clients from OpenAPI specs (@agentic/openapi-to-ts)
• ✅ 100% open source && not trying to sell you anything 💯
