What it can do
Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.
fetchGet 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.
check_linkIs this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.
check_changeDid 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'.
verifyDoes 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.
extractSchema-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.
searchLive web search. Returns a list of {title, url, snippet} results plus which backend served them (free DuckDuckGo by default, or Brave/Serper when configured).
monitorWatch 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.

Common questions
Is SaltCrate Oracle safe?
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 3 days ago, and the latest version (1.1.6) reached the registry 2 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?

Oracle by SaltCrate
Live web intelligence for AI agents — free to start, no key, no signup, no wallet. Seven MCP tools: live search, schema-driven structured extraction, clean page fetch, link checking, change detection, recurring monitoring, and claim verification.
- Endpoint (Streamable HTTP):
https://oracle.saltcrate.com/mcp - Free tier: 200 calls/hour per IP, no `Authorization` header at all — on
fetch,search,check_link,check_change,verifyandmonitor. Point your agent at the endpoint and go. - Beyond the free tier: $0.01/call in USDC (Tempo) on every tool · $0.50/call by card on
extract+monitor(the LLM-backed tools) - No wallet? Prepaid access pass: $5 for 1,000 calls → https://oracle.saltcrate.com/buy
Agent install: llms-install.md has copy-paste configs for Cursor, Cline, VS Code, Claude Code and Windsurf.
Quickstart (zero config)
No key, no account, no payment. Any MCP client:
curl -s https://oracle.saltcrate.com/mcp \-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call", "params":{"name":"search","arguments":{"query":"silver spot price"}}}'
That returns real results. The same endpoint answers fetch, check_link, check_change, verify and monitor the same way, free, up to 200 calls/hour from your IP. When you outgrow the free tier — or want extract — either settle per call (USDC/card, see below) or buy a pass.
Try a single tool in the browser: https://oracle.saltcrate.com/demo?tool=fetch · check_link · search · extract (page → JSON)
Prepaid access pass (60 seconds, card, no wallet)
- Buy a pass: https://oracle.saltcrate.com/buy ($5 → 1,000 calls, valid 12 months)
- Copy the
orc_…key it gives you. - Send it as a bearer token on any call:
curl -s https://oracle.saltcrate.com/mcp \-H "Authorization: Bearer orc_…" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call", "params":{"name":"extract","arguments":{"url":"https://example.com","schema":"{}"}}}'
Check remaining calls: GET https://oracle.saltcrate.com/usage?key=orc_…
Pay-per-call (no account)
A call past the free allowance — or any extract call with no key — returns a -32042 "Payment Required" challenge carrying both rails: USDC via Tempo and, on extract/monitor, a Stripe card charge. The agent pays, retries, and gets the result plus a receipt.
