External tool integration gives an agent a defined way to request work or information from another system. The integration specifies which capabilities are available, what inputs they accept, and what results they return.
A connection should be understood by its actual permissions and interface. Linking one external tool does not automatically expose unrelated applications, browser controls, accounts, or data sources.

External tool integration is like giving an AI helper access to one extra tool in a toolbox. The helper can use that tool for the jobs it supports, but it does not receive every tool you own.
For example, connecting a weather service could let the helper check a forecast, while still giving it no ability to open your browser or send an email.
What should an external tool integration define?
It should define available actions, accepted inputs, returned results, permissions, errors, and any limits that affect use.
Is connecting a tool the same as giving an agent full account access?
No. A well-scoped integration exposes only specific capabilities and authorized data.
