## Tools
- phone_lookup (Phone number intelligence) - Return a supplementary, low-confidence intelligence bundle for a phone number: validity, formatting, line type, range carrier, country, caller name (CNAM, where available), STIR/SHAKEN verstat (supply the call's verstat to fold it into the spam signal), a labeled spam signal, and a first-party do-not-contact (DNC) signal — a suppression preference registered by the number's own owner, never a copy of any government registry. Advisory only — the agent keeps every routing and dialing decision. Endpoint: https://numbers.online/api/v1/mcp
- line_type (Line type) - Return only the deterministic fields for a number — validity, line type (mobile / fixed line / VoIP / …), range carrier, country, and formatting. No paid dip; a free, fast classification a voice agent can call before deciding to enrich. Endpoint: https://numbers.online/api/v1/mcp
- caller_risk (Caller risk signal) - Return a labeled, low-confidence risk read for an inbound caller: a spam signal (0–100, higher = riskier), verstat passthrough, and a first-party do-not-contact (DNC) signal — without a name dip. A supplementary input to the agent's own policy, never a verdict on whether to accept or reject the call. Supply the call's STIR/SHAKEN verstat to fold it into the signal — a failed validation raises the risk. Endpoint: https://numbers.online/api/v1/mcp
- dnc_check (Do-not-contact supplementary signal) - Return a first-party do-not-contact signal (suppress / no_match / unknown) for a number, sourced ONLY from suppression preferences registered and verified by the number's own owner inside Numbers Online — never a copy of any government or licensed do-not-call registry. "suppress" = the owner asked not to be contacted on this channel; "no_match" = no suppression preference on record (absence of suppress is not consent); "unknown" = the number could not be evaluated. Comes with a signed receipt recording the status "as of T". Advisory input to the agent's own process — it does not assert that a call is lawful. Endpoint: https://numbers.online/api/v1/mcp
