Overview

AI-generated overview

Remote MCP server for country calling codes, phone number analysis, dialing guidance, batch normalization and calling-window planning.

What you can do
  • Look up country calling codes by text, ISO code, dial code or region, with optional reviewed dialing examples
  • Analyze, format and compare phone numbers using versioned numbering metadata, including region resolution and input rules
  • Prepare origin-specific dialing instructions and diagnose formatting problems with suggested prefix repairs
  • Normalize up to 100 records in a batch, flagging invalid entries and optional duplicate candidates
  • Find overlapping working hours across explicit IANA time zones and dates, including overnight shifts and DST
  • Check capabilities, coverage, dataset versions and request limits before choosing a workflow
When to use it
Useful when an assistant needs to format or validate international phone numbers, explain how to dial between countries, clean up a list of numbers, or schedule calls across time zones. It is a metadata reference, not a live carrier or subscriber lookup.
Requirements
Remote streamable HTTP endpoint at the provider's site; no package, account, API key, environment variable or header is declared. Network access to the endpoint is required.
Before you install
Results are numbering metadata only: no carrier, HLR/HSS, MNP or live subscriber checks, and equality or region results do not prove ownership or current location. Batch normalization returns errors and duplicate candidates but does not change or store contacts. Dialing results can be network-dependent and conditional.

Installation

In SourceWeft

  1. Open Country Calling Codes in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Kajdep%2Fcountrycallingcodesmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

11

get_phone_capabilities

Phone capabilities

Discover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow.

ParametersoperationcountryCode

analyze_phone_number

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.

ParametersdetailphoneNumberrequirednumberCountryCodeoriginCountryCode

get_dialing_instructions

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.

ParametersdetaildevicephoneNumberoriginCountryCoderequiredcarrierSelectionCodedestinationCountryCoderequired

normalize_phone_numbers

Normalize phone batch

Normalize up to 100 records with unique IDs. Invalid records produce individual errors. Optionally identify canonical duplicate candidates; no contacts are changed or stored.

Takes no parameters.

compare_phone_numbers

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.

ParametersleftrequiredrightrequiredextensionPolicy

resolve_phone_region

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.

ParametersdetailphoneNumberrequirednumberCountryCodeoriginCountryCode

get_phone_input_rules

Phone input guidance

Get reviewed display placeholders and trunk-prefix guidance. Examples are not validation masks. English fallback and unsupported editorial coverage are explicit.

ParameterslocalecountryCoderequired

diagnose_dialing_problem

Diagnose dialing format

Explain formatting issues and propose reviewed prefix repairs for confirmation. Uses the same analyzer. Cannot determine why a network rejected a call.

ParametersdetaildevicesymptomphoneNumberrequirednumberCountryCodeoriginCountryCodedestinationCountryCode

find_calling_windows

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.

Takes no parameters.

lookup_country_calling_code

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.

ParametersqcodelimitregiondialCodeincludeExamples

format_international_phone_number

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.
