Agents that act in every app.
An agent is only as useful as what it can reach. Hoook gives yours thousands of tools across your users' apps, with auth handled, so it can finish the job.

Without Hoook
- Your agent can draft the email but cannot send it
- Each new tool means OAuth, a schema and a handler, built by hand
- Integration work crowds out the agent your customers pay for
- Every API change is a fire drill for whoever built that connector
With Hoook
- Your agent sends it, from the user's own account
- Thousands of tools, typed and described for a model to use
- Your team builds the agent. Integrations come from Hoook
- API changes are absorbed before they reach your users

What Hoook takes off your plate.
Tools on demand
Load only the tools a task needs, so the model stays focused.
Act on behalf of each user
Every call runs with that person's own access, never a shared key.
Wake on events
Triggers start your agent when a ticket, email or payment arrives.
The numbers behind agent integrations
Public documentation from the providers, and our own figures, each labelled with its source.

GitHub REST API documentationBuilt for agents that act.
Model agnostic
Use any model and any framework that can call a function, or MCP.
Approval for writes
Require a person to confirm before a tool changes data.
Breadth on day one
Say yes to the app your user asks for, the same day.
Free to prototype
Build on the Free plan and pay when your users go live.
