Google address validation is a service for verifying, standardizing, and geocoding postal addresses. It helps ensure your address data is accurate and ready for shipping, billing, or compliance.

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 Google address validation account to Claude via Composio Connect, enabling it to validate shipping address before order processing, standardize customer address for CRM records, get geocode for a delivery location, 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.

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 Google address validation account

Back in Claude, ask it to connect to Google address validation or give it any Google address validation-related task.

For example, ask Claude to:

  • "Validate shipping address before order processing"
  • "Standardize customer address for CRM records"
  • "Get geocode for a delivery location"

It will prompt you to authenticate and authorize access.

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

What is the Google address validation Claude Connector, and what's possible with it?

The Google address validation MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google address validation account. It provides structured and secure access to address validation and geocoding services, so your agent can validate, standardize, geocode, and provide feedback on addresses automatically on your behalf.

  • Real-time address validation: Instantly check if an address is accurate, correctly formatted, and deliverable based on Google’s global data.
  • Address standardization: Have your agent automatically reformat and standardize messy or incomplete addresses for consistent records.
  • Retrieve geolocation details: Let your agent determine the latitude and longitude coordinates for any validated address, supporting location-based workflows.
  • Deliverability verdicts: Enable your agent to check whether an address can actually receive mail, helping prevent failed shipments or returns.
  • Automated feedback on validations: Provide structured feedback about address validation attempts, improving future accuracy and reporting.

Troubleshooting

1. Why does Claude not use the Composio connector for Google address validation?

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

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

2. Why does Claude show an MCP server error before Google address validation connects?

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

  • 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 Google address validation.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Google address validation authorization link not work?

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

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

4. Why do Google address validation actions fail after they worked before?

The Google address validation connection can expire or lose permission.

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

5. How do I switch to a different Google address validation account?

Claude can manage the Google address validation connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Google address validation 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 Google address validation.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which Google address validation 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 Google address validation data and credentials are handled as safely as possible.
