The AI landscape is evolving fast, like really fast. Every week we find new tools, new AI Models and new announcements daily. This week is no different with Google’s newly announced Agent2Agent protocol.

The two biggest movements in the AI space, Model Context Protocol (MCP) and Agent2Agent (A2A) are set to revolutionise how all businesses, especially small to mid-sized businesses (SMEs) will be able to automate their workflows. At Design for Online®, we have been already leveraging some of these tools, to streamline internal and client operations, allowing us to expand our services drastically.

The massive potential which is now becoming a reality since the launch of LLMs is growing rapidly. Now agents and automation tools will be, the cliche we seem to be saying each week “game changing” but we really feel different about this one. From Outlook, Slack & Salesforce to designing in Canva and the smart home. Find out why these protocols will matter.

So, what Are MCPs and what is the new A2A? Let’s break it down in as simple terms as possible.

Model Context Protocol is a framework announced by Anthropic, an open standard for connecting AI systems with data sources, replacing fragmented integrations with a single protocol. Currently system to system communication and instructions, most of the time come via API systems where the user has their API key and then they can program or automate a system to do one thing based on whether they are adding, deleting, updating, or any other command built into the API system.

MCPs flip all of this on it’s head, allowing the AI to read your natural language prompt, make the relevant API call via the MCP and the MCP server broadcasts available commands the AI can call on.

MCPs will be game changing – there it is again! We won’t say it anymore, but it is implied. No longer do we need to automate every aspect of the API depending on what we want to do, whether it is to update tasks on Clickup one by one, we can just ask the AI model to update the task or delete the task and it will take care of everything else.

Agent2Agent Protocol announced by Google enables different AI agents to communicate and collaborate, whether they are hosted or not, like a universal language for AI allowing tools to work together seamlessly across platforms. Think of it as the ability for one AI agent which is capable of a task to then go and speak to another AI agent and process requests between each other.

Imagine a customer service AI agent resolving a query by coordinating with a billing agent that can then find the required billing information, then go and check with the stock system, or other systems managed by other services and finally bring it back to the customer.

Why MCP and A2A offer the next step which makes true AI automation possible.

Now we know what they are, let’s talk about how they can be used for your business. Through driving efficiency, reducing overheads and streamlining complex operations, here’s how MCP and A2A deliver:

Smarter, personalised automations with MCP: Imagine an AI tool that remembers your last client conversation, automatically drafts a follow up email in Outlook, tailored to the context. Your team can run these agents at scale that can expand on each individuals capabilities. MCP makes this possible by allowing AI to communicate with systems without advanced integration or API knowledge.

By hosting MCP servers in house, you also keep your data secure and under your control, giving you peace of mind while staying ahead of the competition.

With A2A, picture your AI powered email system, talking with your social media tool, to schedule posts based on client responses, speaking with your analytics agent to gather the best data for use on your social posts, all without lifting a finger. A2A connects different AI agents, enabling them to work together.

From automating client follow ups to managing social media at the right moment, these technologies help you do more with less. They’re ideal for most businesses that are ready to leverage the possibilities of AI as we move forward into unknown territory.

How we are using AI into our systems for ourselves and our clients

We’re already harnessing MCPs throughout our AI automation workflows and can’t wait to integrate A2A as it rolls out, taking our automations to the next level.

We have our own SEO tool called Forerunner which is accessing multiple tools and services using API calls, our MCP servers are also linking into this process to analyse relevant data, backlink analysis and a lot more, all while not programming the system on an API level. Our MCP servers then connect to AI agents, letting us interact with them by voice or text to trigger tasks.

A2A will take this all a step further, allowing our system to integrate effortlessly with existing tools, allowing our automations to work even better, working together, creating a seamless experience. We are building our own tools now too, with the help of AI and our own API service, allowing our services to be managed by agents in the future, as our services expand we take on the extremely powerful capabilities being made possible.

Our goal? To take the hassle out of digital tasks so you can focus on growing your business, while scaling further than before and empowering staff to leverage AI With MCP and A2A, we’re building solutions that are as intelligent as they are easy to use.
