Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 422 ms.

    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name saltcrate-oracle.

  • Pass
    Lists tools

    tools/list returned 7 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 425 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 428 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

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.

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 9 parameters have a description (0%). The bar is 80%.

    Website matches publisher

    The website host does not match 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

Capabilities

Tools 7

check_change

Did this web page change since the last time it was checked? Hash-based change detection. First check reports 'new'; later checks report 'changed' or 'unchanged'.

Discovered
check_link

Is this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.

Discovered
extract

Schema-driven structured extraction: fetch a URL and map its content into typed entities that conform to a JSON Schema you provide. Pass the schema as a JSON string; returns schema-conforming JSON (e.g. pricing, company facts, product specs, events). Requires DEEPSEEK_API_KEY.

Discovered
fetch

Get clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content. Returns the text plus title, content-type, HTTP status, and length.

Discovered
monitor

Watch a URL over time — call periodically and pay per check. First call reports 'new'; later calls report 'changed' or 'unchanged', with changes_since_first_seen, first_seen, and last_checked timestamps for recurring monitoring.

Discovered
search

Live web search. Returns a list of {title, url, snippet} results plus which backend served them (free DuckDuckGo by default, or Brave/Serper when configured).

Discovered
verify

Does this source URL support a given claim? Returns a confidence score, matched terms, and the best supporting excerpt. Heuristic term-overlap — not semantic fact-checking.
