Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Genderize account to Claude via Composio Connect, enabling it to predict gender for a single first name, analyze gender breakdown for a list of names, estimate gender distribution by country for event guests, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Genderize account

Back in Claude, ask it to connect to Genderize or give it any Genderize-related task.

For example, ask Claude to:

  • "Predict gender for a single first name"
  • "Analyze gender breakdown for a list of names"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Genderize account is ready to use.

What is the Genderize Claude Connector, and what's possible with it?

The Genderize MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Genderize account. It provides structured and secure access to gender prediction tools, so your agent can perform actions like analyzing names for gender, running batch predictions, and localizing results by country—all seamlessly on your behalf.

  • Single name gender prediction: Instantly determine the likely gender of any first name your agent encounters, complete with statistical confidence.
  • Batch gender analysis: Predict genders for a list of first names in one go, perfect for analyzing datasets or email lists efficiently.
  • Localized gender estimation: Enhance accuracy by predicting gender based on both name and country code, adapting results to regional naming trends.
  • Automated demographic tagging: Let your agent enrich contacts, surveys, or user lists with gender predictions to streamline data categorization and profiling.
  • Statistical breakdowns and probability scores: Access probability statistics for each prediction, allowing your agent to make informed decisions in downstream workflows.

Troubleshooting

1. Why does Claude not use the Composio connector for Genderize?

The connector can show as connected, but Claude must use it in each Genderize conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Genderize again.

2. Why does Claude show an MCP server error before Genderize connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Genderize.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Genderize.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Genderize authorization link not work?

The Composio connector is one server. Your Genderize account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Genderize connection.
  • Composio creates a fresh Genderize authorization link.
  • Open that link in your browser and finish the Genderize sign-in.

4. Why do Genderize actions fail after they worked before?

The Genderize connection can expire or lose permission.

  • Ask Claude to inspect the Genderize connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Genderize account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Genderize.
  • If the action still fails with a permission error, check that the connected account has that permission in Genderize itself.

5. How do I switch to a different Genderize account?

Claude can manage the Genderize connection for you.

  • Ask Claude to disconnect or delete the current Genderize account.
  • Ask Claude to connect Genderize again.
  • Open the new Composio authorization link for Genderize.
  • Sign in with the other Genderize account in the browser.
  • After the account connects, ask Claude to retry the Genderize task.

6. Why is my Genderize connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Genderize connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Genderize tools still do not appear, click , disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Genderize.

FAQ

Frequently asked questions

With a standalone Genderize MCP server, the agents and LLMs can only access a fixed set of Genderize tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Genderize and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Genderize tools.

Yes, absolutely. You can configure which Genderize scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Genderize data and credentials are handled as safely as possible.
