Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 86 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name tier-1-agent-context.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 86 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 86 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    8 of 8 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-09T02:42:45.399667Z, within 180 days.

Capabilities

Tools 4

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.

Discovered
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.

Discovered
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.

Discovered
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.
