Nothing serious here today

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

Available tools 7

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

change

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'.

extract

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.

fetch

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.

link

check_link

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

monitor

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.

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).

verify

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.

SaltCrate Oracle — questions

Answers built from our own checks of this server.

What can SaltCrate Oracle do?

It exposes 7 tools, read directly from the server on our last check. Among them: check_change, check_link, extract, fetch, monitor, search and 1 more. 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 SaltCrate Oracle working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 458 ms. The bar chart above shows every period we have measured.

How do I connect SaltCrate Oracle?

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.

Does SaltCrate Oracle need an API key?

No. SaltCrate Oracle completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SaltCrate Oracle?

It answers our handshake in 458 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is SaltCrate Oracle open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at saltcrate-oracle.fly.dev, which runs on its operator's own terms.
