Human-in-the-loop for AI agents

Give your agent someone to ask.

Add one MCP entry. Your agent asks, your phone buzzes, your answer goes straight back.

Your agent asks, then waits

At a decision it should not make alone, your agent asks a question and waits. It picks up again when you answer.

  • It waits for you

    The agent pauses at the question and holds its place. When you answer, it carries on with your decision, not a guess.

  • Questions that fit the decision

    Pick single-select, multi-select or free text. Send up to 10 questions in one push and answer them in one go.

Answer from your phone, wherever you are

A push notification tells you what the agent asked. Choose or type your answer and it goes straight back.

How it works

Add one MCP entry

Paste a JSON entry into Claude Code or add the connector URL in Claude.ai. Each project has its own secret key.

Your agent asks

The agent calls ask_question or ask_questions. Your iPhone gets a push notification.

Answer from your phone

Tap your choice or type a reply. The agent, waiting on the thread, receives it and carries on.

Built for agents that need a person

Six MCP tools

Send, ask, ask a batch, wait, check and upload. Your agent calls them like any other MCP tool.

One secret key per project

Each project gets its own key, shown once when you create it. Keep it somewhere safe.

Remote over HTTP

Your agent connects to the hosted endpoint at mcp.notifexapp.com. No server to run.

Connect with a single MCP entry

Claude Code takes a JSON entry. Claude.ai takes a connector URL. That is the whole setup.

  • Two ways to connect

    Add the entry to Claude Code, or paste the connector URL into Claude.ai. Both use your project's secret key.

Send files, find every thread

Agents can attach what they mean, not just describe it. Every question and answer stays in your inbox.

  • Agents send files

    Images, video and documents, up to 10 files and 10 MB each. See the screenshot or log the agent means.

  • Inbox and search

    Every project keeps its threads in one inbox. Search to find what an agent asked and what you said.

Get Notifex on your iPhone before your agent needs to ask
