Basic information
Read-only 11-tool MCP server and JSON API for international phone numbers, country calling codes, phone capabilities, dialing instructions, regions, and calling windows. Official Registry v1.4.0; hosted via Streamable HTTP with no authentication.
https://www.countrycalling.codes/api/mcpclaude mcp add countrycallingcodesmcp --transport http https://www.countrycalling.codes/api/mcpDiscover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow.
Analyze a number using versioned numbering metadata. National numbers need numberCountryCode; exit prefixes need originCountryCode. Reports uncertainty and rule evidence, never live subscriber status.
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.
Normalize up to 100 records with unique IDs. Invalid records produce individual errors. Optionally identify canonical duplicate candidates; no contacts are changed or stored.
Compare two numbers after analysis. Missing context produces indeterminate. Extensions must match unless extensionPolicy is explicitly ignore; equality does not establish ownership.
Resolve a phone number to metadata-backed country candidates or non-geographic numbering. Results are numbering assignments, not current location or carrier.
Get reviewed display placeholders and trunk-prefix guidance. Examples are not validation masks. English fallback and unsupported editorial coverage are explicit.
Explain formatting issues and propose reviewed prefix repairs for confirmation. Uses the same analyzer. Cannot determine why a network rejected a call.
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.
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 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.
CountryCallingCodes is a read-only MCP server for international phone-number and country-calling-code data. Official Registry v1.4.0 exposes 11 tools over the hosted Streamable HTTP endpoint https://www.countrycalling.codes/api/mcp.

No local setup is required.
The service is read-only and requires no authentication. Documentation: https://www.countrycalling.codes/developers.
The CountryCallingCodes remote MCP server is a hosted Model Context Protocol endpoint at https://www.countrycalling.codes/api/mcp, so AI assistants can connect to it without installing or running anything locally.
Add the endpoint https://www.countrycalling.codes/api/mcp to any MCP-compatible client such as Claude Code, Cursor, or VS Code. The setup snippets on this page configure each client in one step.
No. CountryCallingCodes's MCP server does not require authentication — you can connect directly with the endpoint URL.
CountryCallingCodes exposes a streamable-http endpoint, the transport used by remote MCP servers and supported by all major MCP clients.
One MCP connection for all your Gmail, Google Calendar, Drive and Contacts accounts, Slack workspaces and Notion — free.
