An application connector wraps an external service's authentication, data model, and actions in tools that another system can use. A calendar connector might expose event search, event creation, updates, deletion, availability, and recurrence through structured inputs and outputs.
Connector reliability depends on complete results, correct permissions, stable identifiers, error handling, and verification of changes. Source data remains untrusted, and consequential actions should be visible and bounded by the user's granted authority.

An application connector gives an AI system controlled access to data or actions in another service, such as email, cloud storage, a calendar, or a document editor. It translates the service's interface and authorization into tools the AI can use.
For example, a calendar connector may let an agent read free times and create meetings for one approved account. Its usefulness and risk depend on exactly which records and actions it exposes, so permissions and sensitive changes need clear limits.
