Nothing serious here today

Today is the operative word: we check Tier 1 Protocol every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

authorize

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

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.

render

render_context_results

Inspect 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 required.

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.

Tier 1 Protocol — questions

Answers built from our own checks of this server.

What can Tier 1 Protocol do?

It exposes 4 tools, read directly from the server on our last check. Among them: authorize_sources, fetch, render_context_results, search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Tier 1 Protocol working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 127 ms. The bar chart above shows every period we have measured.

How do I connect Tier 1 Protocol?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Tier 1 Protocol need an API key?

Yes. Every time we knock, Tier 1 Protocol answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Tier 1 Protocol?

It answers our handshake in 127 ms on average, which is faster than 88% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Tier 1 Protocol open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
