5 Tools

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 Genderapi io account to Claude via Composio Connect, enabling it to determine gender from a customer email address, infer gender based on a given username, get gender prediction for full names in a CSV, 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.

Connecting Genderapi io to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Genderapi io account

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

For example, ask Claude to:

  • "Determine gender from a customer email address"
  • "Infer gender based on a given username"
  • "Get gender prediction for full names in a CSV"

It will prompt you to authenticate and authorize access.

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

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

The Genderapi io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Genderapi io account. It provides structured and secure access to gender identification services, so your agent can perform actions like inferring gender from names, emails, or usernames, checking usage statistics, and validating API errors on your behalf.

  • Gender inference from first names: Your agent can determine the likely gender associated with a given first name, supporting localization for more accurate results.
  • Gender prediction from email addresses: Easily infer gender from a provided email address, enabling smart personalization workflows after obtaining proper consent.
  • Analyze usernames and full names for gender: Let your agent deduce gender from usernames, nicknames, or full names—even when only partial information is available.
  • Account usage and API credit monitoring: Check remaining GenderAPI.io credits and expiry dates so you never run out of quota unexpectedly.
  • Comprehensive error code listing: Retrieve and understand all possible API error codes to streamline debugging and ensure robust integrations.

Troubleshooting

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

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

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

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

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

  • 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 Genderapi io.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Genderapi io authorization link not work?

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

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

4. Why do Genderapi io actions fail after they worked before?

The Genderapi io connection can expire or lose permission.

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

5. How do I switch to a different Genderapi io account?

Claude can manage the Genderapi io connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Genderapi io 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 Genderapi io.

FAQ

Frequently asked questions

With a standalone Genderapi io MCP server, the agents and LLMs can only access a fixed set of Genderapi io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Genderapi io 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 Genderapi io tools.

Yes, absolutely. You can configure which Genderapi io 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 Genderapi io data and credentials are handled as safely as possible.
