Category Security
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability68
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 902 tokens (~225/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
verify_business ~209
Is this company or domain legit? Business and domain verification (KYB) for vendor screening, supplier checks and scam or fraud review: domain age and registrar from RDAP, DNS (A/MX/NS), email security (SPF/DMARC) and HTTPS. Returns a verdict and a 0-100 trust score with evidence URLs, and flags newly registered or thin-infrastructure domains, a common scam signal. Use it before your agent pays an invoice, onboards a vendor or trusts a site. Signed attestation. Bulk: /verify/business/batch. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.05 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/business over HTTP. Same price on either transport.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Domain to verify, e.g. example.com |
No output schema declared.
No examples provided.
verify_claim ~168
Is this claim true? Fact-check a single factual claim or statement against live web evidence before your agent relies on it. A fact-checking oracle, hallucination guard, and grounding and citation check for misinformation review: returns a verdict (supported / contradicted / insufficient), a confidence score, and source citations, as a signed attestation your agent can cite. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.25 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/claim over HTTP. Same price on either transport.
| Name | Type | Req | Description |
|---|---|---|---|
| claim | string | yes | A single factual claim, 8-600 characters |
No output schema declared.
No examples provided.
verify_freshness ~209
Website uptime and change check: is this URL up right now, and has the page changed? Fetches the URL and returns the HTTP status, Last-Modified and ETag headers, a SHA-256 fingerprint of the content, and whether it changed versus a hash you pass in. Use it to check a site is live, detect stale data, monitor a page for changes, or decide whether to invalidate a cache before your agent acts on what it says. Returns a signed attestation. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.02 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/freshness over HTTP. Same price on either transport.
| Name | Type | Req | Description |
|---|---|---|---|
| prior_hash | string | – | Optional prior SHA-256 hex to compare against |
| url | string | yes | Full URL including https:// |
No output schema declared.
No examples provided.
verify_price ~209
Crypto price check: the current spot price of Bitcoin (BTC), Ethereum (ETH), Solana (SOL) or any token ticker in USD, cross-checked across five exchanges (Coinbase, Kraken, OKX, Binance, CoinGecko). Returns the median price, the spread between venues and a divergence flag, as a signed price oracle attestation your agent can cite. Use it before your agent trades, quotes, values a portfolio or settles on a token price. Needs at least two live quotes; a ticker no venue lists is not charged. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.02 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/price over HTTP. Same price on either transport.
| Name | Type | Req | Description |
|---|---|---|---|
| symbol | string | yes | Ticker symbol, e.g. BTC, ETH, SOL |

How do I install the com.402oracle/402oracle MCP server?
com.402oracle/402oracle is a hosted endpoint at https://402oracle.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
