Tools of Tier 1 Protocol
	Description		Read-only	Idempotent	Open world
`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.

`fetch`Paid 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.	Paid exact-span retrieval after Tier 1 search. Accept only an unchanged id returned by search for the same account.

`index`Index one file into the user's own Tier 1 library, one batch at a time. Pass the file's text as the chatbot read it, with its SHA-256 as the idempotency key — re-indexing the same bytes is a no-op. One call carries at most 64 KiB of text; larger files are split and indexed in successive calls. This is the conversational drip path: it builds the index file by file as the user works. It cannot bootstrap a large existing library — for a library, use the browser indexer page or Local. Authentication and an active paid plan are required. The user's keyed profile (derived locally, sent per request) is also required.	Index one file into the user's own Tier 1 library, one batch at a time.

`index_status`How much of the user's library is indexed, and whether the index is still growing. Returns the sources indexed, the batches still pending, and the index fingerprint. Poll this after indexing, never the index directly. Authentication and an active paid plan are required. The user's keyed profile (derived locally, sent per request) is also required.

`index_upload_token`Mint a short-lived upload token so the user can upload a browser-built index to their Tier 1 library. The token is valid 15 minutes for any number of sources under this principal and profile. The response includes the token AND the principal_id: hand the user BOTH to paste into the indexer page (token field + principal field) — the page never collects a principal_id on its own, and the library compares the token's principal to the upload body's principal_id. The token travels in the x-tier1-upload-token header. Authentication and an active paid plan are required. The user's keyed profile (derived locally, sent per request) is also required — only its fingerprint is bound into the token.

`render_context_results`Inspect one to six exact coordinates returned by paid Tier 1 search. Pass only unchanged result ids.

`search`Retrying 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.	Retrying the same public search with the same MCP request identity replays the same bounded operation.
