authorize_sources
Add selected private ChatGPT files to the paid account's Tier 1 context. Show the filenames and fixed 30-day retention and require explicit confirmation before calling. This upload consent applies to private file intake only; it does not define or narrow the other policy-eligible catalogs Tier 1 may route. Authentication and an active paid plan are required.
Files the signed-in user selected in ChatGPT for Tier 1 to route.
The fixed retention period for this authorization.
Must be true only after the user explicitly confirms that Tier 1 may retain and route these files for 30 days.
This tool isn't marked read-only, so it may change something on the server or in an account you connected.

}searchRetrying the same public search with the same MCP request identity replays the same bounded operation. Paid context routing for useful work. Route a question across policy-eligible Tier 1 context available to the account, including private, shared, licensed, or public catalogs when present. Returns up to ten verified excerpts, exact source coordinates, signed result ids, and reference URLs. Broad questions may need focused follow-up searches; absence from one result set does not establish absence from the corpus. Authentication and an active paid plan are required. This is not an unrestricted web crawler and cannot change files.
