Every app, in any agent, from one URL.
Hoook hosts MCP servers for thousands of apps. Point Claude, ChatGPT or your own agent at one address and it can act in every app the user has connected, with scoped auth and a log of every call.
Connect. Permit. Act.
1. Connect
The user signs in to Slack, GitHub, HubSpot or any other app through Hoook.
2. Permit
Choose which apps and tools the agent may use, and which actions need approval.
3. Act
Any MCP client calls the tools. Hoook attaches the auth and logs the call.
Ask it to do the work, not describe it.

The model never sees a secret
Tokens stay encrypted in Hoook. The agent only sees inputs and results.
Scoped to one user
Every call runs with the account and permissions of the person who connected it.
Approval on writes
Reads flow freely. Sends, deletes and payments can wait for a yes.
A full audit trail
Every call is logged with the user, the tool, the inputs and the result.
Two minutes. One address.
