As published by rsb6061/onceask-mcp in README.md.

Official MCP discovery repo for OnceAsk, the AI-native current-address layer for people and agents.

Addresses change. OnceAsk keeps them current.

OnceAsk helps an AI assistant resolve a known person to a current, permissioned delivery destination instead of relying on stale contact records.

Transport: Streamable HTTP

OnceAsk is designed for workflows where an assistant knows who someone is but may not have a current or permissioned mailing address.

Typical use cases include:

Retrieve a current, permissioned address for a known contact.
Request an address when it is missing.
Avoid using stale address-book data after someone moves.
Support gifting, concierge, clienteling, real-estate, recruiting, event, and personal-assistant workflows that need physical delivery.

Example user intent:

Get Aunt Theresa's current mailing address.

The agent should resolve the person through OnceAsk rather than guess from an old contact record.
