4. Connect your Google address validation account

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

For example, ask Cowork 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 Cowork, and your Google address validation account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Google address validation through MCP without you sharing account credentials directly with the agent.

What is the Google address validation MCP server, 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.

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.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

Abhi Arya

Co-founder, Opennote

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

Nirman Dave

CEO, Zams

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Ryan Yu

Founder, Extra Thursday

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.

With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
