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 w…
authorize_sourcesAdd 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-eligibl…
fetchPaid exact-span retrieval after Tier 1 search. Accept only an unchanged id returned by search for the same account. Authentication and an active paid plan are required. Do not invent ids, browse nearby text, or change files.
render_context_resultsInspect one to six exact coordinates returned by paid Tier 1 search. Pass only unchanged result ids. Tier 1 rehydrates and revalidates each id for the same account; caller-supplied titles, excerpts, URLs, and coordinates are rejected. Authentication and an active paid plan are r…
