@pushary/ai-sdk

Human-in-the-loop for the Vercel AI SDK. Give your agent one tool that pauses until a real human approves on their phone, and answers from the lock screen.

Two calls is the whole integration:

1. enroll(externalId) once per end-user. Show them the link it returns. One tap connects their phone.
2. Add createPusharyTools({ externalId }) to your agent. Now it can ask that person and block on the answer.

No UI to build, no polling to write, no webhooks required. Requires the Pushary Partner plan.

Install

npm i @pushary/ai-sdk ai zod

Set PUSHARY_API_KEY (get it in your dashboard).

Connect an end-user's phone (once)

import { enroll } from '@pushary/ai-sdk'

const { universalLink } = await enroll({ apiKey: process.env.PUSHARY_API_KEY! }, user.id)
// Show universalLink to the user as a button or QR. One tap turns on approvals.
// Cache the fact that they enrolled, not the link itself (it is single-use).

Give your agent a human to ask

import { generateText, stepCountIs } from 'ai'
import { openai } from '@ai-sdk/openai'
import { createPusharyTools } from '@pushary/ai-sdk'

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools: createPusharyTools({
    apiKey: process.env.PUSHARY_API_KEY!,
    externalId: user.id, // the enrolled person who answers
  }),
  stopWhen: stepCountIs(10),
  prompt: 'Issue the refund only if a human approves it.',
})

The agent gets an askHuman tool. When it calls it, the person gets a push notification and approves, declines, picks an option, or types an answer from their phone. The tool blocks until they reply, then hands the model an unambiguous result.

Behavior that matters

• Fail-closed. A declined, expired, or unanswered confirm is reported to the model as "not approved, do not proceed." Approval only happens on an explicit yes.
• Serverless-safe. Each ask blocks up to 55 seconds by default (timeoutMs). The decision stays answerable for its full lifetime, so a slow human still resolves it. For waits of minutes or hours, run under a durable workflow (Inngest, Temporal, Vercel Workflow) and use a callbackUrl.
• No double-asks on retry. The idempotency key is derived deterministically, so a retried step reuses the same decision instead of paging the human twice.

API

createPusharyTools(config)

config: { apiKey, externalId, agentName?, timeoutMs?, baseUrl? }. Returns { askHuman }, a tool you pass to generateText / streamText. Merge it with your own tools:

tools: { ...createPusharyTools({ apiKey, externalId }), ...myOtherTools }

enroll(config, externalId)

config: { apiKey, baseUrl? }. Returns { token, deepLink, universalLink, expiresInSeconds }.

Under the hood

This package is a thin wrapper over @pushary/server (enroll + decisions.ask). Use that directly for any framework, or reach for the Pushary MCP server to wire agents up with no code at all. See the adapters guide.
