Make sure your AI agent can validate addresses with Swiftcomplete’s MCP server

Is your business using AI agents to automate customer service, manage bookings, or streamline other processes? If so, it’s important they can validate addresses quickly and correctly.

Swiftcomplete is an address validation solution built for speed, flexibility, and optimised for the era of AI. We’ve created a Model Context Protocol (MCP) server so you can easily add instant address validation to your AI agents.

Why AI agents need address validation
From CRM bots to travel planners and personal shopping assistants, many AI-powered tools need to collect and verify address data. The problem? AI-generated outputs can miss key information, be based on outdated sources, or hallucinate non-existent addresses entirely.

Poor address data can lead to inaccurate customer records and other issues like orders being misrouted, causing failed deliveries. In the example below, Gemini accepted an address without recognising that the supplied postcode had one digit wrong.

What is an MCP server?

Model Context Protocol (MCP) is an open standard designed to connect AI models with external tools and APIs. Think of it as the USB-C of AI: a simple and universal way to plug models into everything from design tools to data services.

For developers, it means:

No need to create custom integrations
Standardised API access
Seamless interaction between AI and relevant tools or data

With Swiftcomplete’s address validation now available via MCP, it’s easier than ever to give your agents instant access to accurate and comprehensive address data.
