# url-oracle — URL Trust Oracle

> Flags phantom-squatted/typosquatted domains and known-malicious URLs before an agent follows them.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "url-oracle": {
      "type": "http",
      "url": "https://url-oracle.fly.dev/mcp"
    }
  }
}
```


## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 35
- drivers: +reachable +uptime-100% +updated-18d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: verify_url (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 322 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 1, about 322 tokens to load them all
- tool set hash: e7203921701744bd3435a12751409b1d
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.julian-martin89/url-oracle.svg)](https://protogrid.dev/servers/io.github.julian-martin89/url-oracle)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `verify_url`: URL Trust Oracle. Call this BEFORE fetching, citing, recommending, or following any URL you were not given directly by the user (one you generated, recalled, or inferred). LLMs routinely hallucinate plausible-looking URLs for documentation, APIs, and brands — attackers pre-register those exact domains and serve phishing/malware to whoever follows them ('phantom squatting'). This tool checks the domain's RDAP registration (does it exist, how old is it), runs a Levenshtein-distance brand-similarity check against well-known domains, and checks the exact URL against a known-malicious-infrastructure blocklist. Returns a synthetic verdict: ALLOW (no issues found), WARN (proceed with caution — read the findings), or BLOCK (do not fetch or cite this — likely a hallucinated/squatted domain or confirmed malicious URL). First 5 calls per caller are free; after that this tool requires x402 payment (USDC on Base) and will return a payment-required error with the amount and address to pay.
