More Details Connect to Claude

Connect your AI agent to the Genderize.io database to automate gender estimation through the Model Context Protocol (MCP). Genderize.io is a specialized API that provides statistical probabilities for the gender associated with any first name, backed by a database of over 114 million records. This MCP server enables you to estimate genders for single or multiple names, localized by country, directly through natural conversation.

Key Features

  • Gender Estimation — Predict whether a first name is associated with a male or female identity based on global data.
  • Statistical Probability — Retrieve certainty scores (0.0 to 1.0) and the total data count used for each prediction.
  • Country Localization — Localize results by providing ISO country codes (e.g., 'US', 'BR', 'GB') to improve accuracy for regional naming patterns.
  • Batch Processing — Estimate genders for up to 10 names in a single request to process lead lists faster.
  • Regional Helpers — Quickly check names for specific countries like the USA, Brazil, UK, Spain, and France using dedicated tools.
  • No-Auth Free Tier — Start using the service immediately with up to 100 free requests per day without an API key.
  • Scale with API Keys — Optionally provide an API key to access higher rate limits for large-scale data enrichment.
