Tools

• analyze_phone_number ~190 tokens
  Analyze a number using versioned numbering metadata. National numbers need numberCountryCode; exit prefixes need originCountryCode. Reports uncertainty and rule evidence, never live subscriber status.
• compare_phone_numbers ~251 tokens
  Compare two numbers after analysis. Missing context produces indeterminate. Extensions must match unless extensionPolicy is explicitly ignore; equality does not establish ownership.
• diagnose_dialing_problem ~254 tokens
  Explain formatting issues and propose reviewed prefix repairs for confirmation. Uses the same analyzer. Cannot determine why a network rejected a call.
• find_calling_windows ~78 tokens
  Find overlapping working hours using explicit IANA time zones and dates. Handles overnight shifts and DST; never infers location from phone numbers or contacts participants.
• format_international_phone_number ~202 tokens
  Normalize a phone number into a plausible international format using reviewed country-specific rules. Processing is ephemeral. This tool does not query carriers, HLR/HSS, MNP databases, or live subscribers.
• get_dialing_instructions ~246 tokens
  Prepare origin-specific dialing guidance for reviewed countries. Provide origin and destination separately; no phone number returns safe placeholder patterns. Network-dependent results remain conditional.
• get_phone_capabilities ~183 tokens
  Discover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow.
• get_phone_input_rules ~142 tokens
  Get reviewed display placeholders and trunk-prefix guidance. Examples are not validation masks. English fallback and unsupported editorial coverage are explicit.
• lookup_country_calling_code ~314 tokens
  Look up international country calling codes by free text, ISO code, dial code, or region. Optionally return reviewed, source-linked dialing examples. This tool does not verify live subscriber numbers.
• normalize_phone_numbers ~79 tokens
  Normalize up to 100 records with unique IDs. Invalid records produce individual errors. Optionally identify canonical duplicate candidates; no contacts are changed or stored.
• resolve_phone_region ~178 tokens
  Resolve a phone number to metadata-backed country candidates or non-geographic numbering. Results are numbering assignments, not current location or carrier.
