Phone Carrier Detector

Phone Carrier Detector is an MCP server that identifies telecommunications carriers and geographic location metadata for mainland Chinese mobile phone numbers. It connects directly to a local in-memory database of over 492,000 Chinese phone prefix records without requiring external third-party API keys. Software developers, data analysts, and automated support agents use this tool to validate user contact details, parse operational regions, and segment messaging lists. The server supports identification for primary Chinese telecommunications networks, including China Mobile, China Unicom, China Telecom, China Broadnet, and China Tietong, as well as mobile virtual network operators. By processing requests via Model Context Protocol tools, it enables LLMs to perform both single-number analysis and batch lookups for up to 100 phone numbers simultaneously. The tool yields standardized JSON responses with network operator names, administrative provinces, cities, and specific dial prefixes, enabling rapid local validation for communications workflows.
