Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

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.

Schemas: list_tools.
