The Rise of Agentic Microservices: What It Means for Your Business

If you’re like most operators in the automotive aftermarket, you’re probably hearing a lot of buzz about AI agents and something called MCP. It can all sound a little abstract or futuristic. But here’s the real story: agentic microservices and machine communication protocols (MCP) aren’t science fiction. They’re the next evolution of how work gets done. And they’re going to make your life a whole lot easier.

In this post, I’ll break down what this means in plain English, why it matters for businesses like yours, and how you can start thinking about using this shift to your advantage.

First: What Are Agentic Microservices?

Traditionally, businesses use microservices:small, modular apps that each do one thing well, like checking inventory or processing orders. They’re powerful because they’re flexible and scalable.

But agentic microservices take this a step further. Instead of just sitting around waiting for someone to push a button or write code to trigger them, these services act more like digital coworkers. They use AI to understand your intent, make decisions, and even take action without you having to hand-hold them.

Think of it this way:

• A microservice is like a vending machine. Push the right buttons, get a result.
• An agentic microservice is like an assistant. Tell them what you need, and they figure out the best way to get it done.

Let’s say you want to know: "Which brake pads are selling fastest in the Southeast region, and do we have enough in stock?" An agentic system can:

• Understand the question
• Pull data from your sales platform, inventory database, and regional location tags
• Deliver a complete answer
• Recommend a reorder if needed

No dashboard digging. No manual spreadsheet pulling. Just real, usable insight.

What the Heck Is MCP?

MCP stands for Model Context Protocol. It’s a standard that helps AI agents talk to your tools and data in a clean, safe, and structured way.

The best analogy I’ve seen: MCP is like USB-C for AI. One port, many connections. Instead of writing custom code for every system, you can plug tools into an MCP layer and let AI agents talk to them in a standard language. MCP ensures that:

• Agents get the right data
• Data access is secure and auditable
• You avoid the spaghetti mess of one-off integrations

At Tromml, we’re using similar concepts to help teams query data using plain English, get real-time alerts, and automate root cause analysis. MCP makes that possible behind the scenes by letting our agents talk to the systems you already use:ERP, POS, inventory databases, and more.

Why This Matters for the Automotive Aftermarket

Here’s the reality: our industry is sitting on mountains of data, but most of it is trapped. It’s hard to access, slow to work with, and usually stuck in silos. Teams spend more time pulling reports than making decisions. That’s where agentic systems shine.

Let’s look at how Tromml is already putting this to work:

1. Classifying Sales Notes Automatically

• Every day, sales reps enter notes in their own style. Instead of needing managers to manually review them, Tromml uses microservices to classify those notes in real-time:tagging intent, urgency, and even customer sentiment.
• This helps leaders spot at-risk accounts, common objections, and opportunities to coach reps based on real conversations:not just sales numbers.

2. Searching the Web to Classify and Benchmark Products

• When reps or buyers are evaluating a new product line, our agents can automatically search public sources:eCommerce sites, forums, competitor listings:and return back structured comparisons: pricing ranges, common use cases, and perceived quality.
• This turns hours of research into minutes, giving your team a faster path to insights.

3. Updating Tracking Numbers Across Systems

• In operations, it’s not uncommon for tracking numbers to live in one system and orders in another. We use agentic services to match, validate, and push tracking data into your order system, so your team doesn’t have to copy and paste or chase down status updates.

And this is just the start. In the near future, we imagine:

• Agents that monitor vendor fill rates and proactively flag patterns that could cost you
• Services that watch for delayed shipments and communicate ETAs to customers automatically
• AI-powered planners that recommend seasonal stocking adjustments based on weather, regional trends, and promotion data

Okay, So How Does This Actually Work?

Behind the scenes, agentic microservices use a few key ingredients:

• Natural language processing to understand your questions or goals
• Orchestration logic to decide which tools or systems to query
• MCP or similar protocols to securely pull that data and format it in a useful way
• Memory and context to stay aligned with the user over time (e.g. understanding which territory a sales rep covers)

This sounds complex, but the goal is to make the interface simpler than ever. You talk to the system like you’d talk to a smart assistant or teammate. The AI handles the heavy lifting in the background.

Where to Start

If this is all sounding a little ambitious, don’t worry:you don’t need to overhaul everything overnight. Here’s where I recommend starting:

1. Identify Repetitive WorkflowsLook for places where your team is constantly pulling reports, checking multiple systems, or copy/pasting into spreadsheets. That’s low-hanging fruit for agentic automation.

2. Focus on a High-Impact Use CaseCustomer insights, sales enablement, and inventory alerts are often a great first step. One small win can build momentum and internal buy-in fast.

3. Prioritize Tools That Can “Talk”Whether or not you're using MCP specifically, pick tools with open APIs, structured data, and flexible integrations. That’s what lets AI agents work their magic.

4. Partner With Solutions Built for Your IndustryThat’s where Tromml comes in. We’re building agent-powered tools designed specifically for the automotive aftermarket. We don’t expect you to become an AI expert:we bring the technology, context, and playbook so your team can act faster and smarter without needing to be data analysts.

Final Thoughts

At its core, this shift isn’t about replacing people:it’s about empowering them. Giving your teams faster answers, better context, and the ability to take action without chasing down data across five systems. It’s about turning insight into impact, and building a more modern, agile business in the process.

Agentic microservices and MCP protocols are the infrastructure for that future. And it’s not some far-off vision. It’s already happening.

Let’s build it together.
