What it can do
| Tool | What it says it does |
|---|---|
analyze_phone_number | 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 | 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 | 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 | 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 | 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 | 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 | Discover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow. |
get_phone_input_rules | 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 | 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 | 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 | Resolve a phone number to metadata-backed country candidates or non-geographic numbering. Results are numbering assignments, not current location or carrier. |
In its maker's words
Calling codes, phone analysis, dialing guidance, batch normalization and calling windows.
