Preview allows you to expose services to the assistant via API or MCP, without a new application. See scope of tools, authentication and confirmation.
Direct answer
Meta introduced Meta AI Connectors in developer preview as a way to connect a service to Meta AI via API or MCP server. The company describes the connector as a set of tools that the assistant can call on AI glasses, app and web, without requiring a new SDK or dedicated app. For business use, the advantage is to bring existing services to a conversational interface; the risk is to allow ambiguous or excessive actions. Each tool must have bounded schema, user authentication, impact-proportional confirmation, idempotence, and audit trail.
Tool is a contract of action
Name, parameters, permissions and result must be unambiguous. An overly generic function transfers critical decisions to the model.
Authentication must represent the person
The connector must not use a broad shared credential. Per-user and expiration scopes reduce the scope for error or abuse.
Confirmation accompanies consequence
Querying status can be automatic; purchasing, sending, deleting or changing requires clear confirmation at the time of action.
Conversation does not eliminate fault states
Timeout, duplication and partial response continue to exist. Idempotence, reconciliation, and short messages help in non-full-screen environments.
Nexus Reading
Start with queries and reversible actions, measure understanding and error, and only then expand the catalog. The assistant must speed up the service without hiding responsibility.
FAQ
Is it necessary to create an app for the glasses?
Meta claims the connector links the service to the assistant without a new SDK or dedicated app.
Does the preview only work on glasses?
No. Meta starts with AI glasses and Meta AI in the app and on the web.
MCP eliminates the need for authentication?
No. The protocol describes tools; authorization and identity remain the responsibility of integration.
