In this week’s In-Ear Insights, let’s talk about MCP—Model Context Protocol—and its applications for marketing and what it means. Katie, you said you have questions.

Katie Robbert – 00:13

I do. I saw you posted in our free Slack group, Analytics for Marketers, towards the end of last week that one of the models had MCP available. When I see notifications like that, my first thought is: Is this something I need to pay attention to? Usually, you’re really good about letting me know, but I am a fully grown human who needs to be responsible for what I should be paying attention to and not just relying on the data scientist on my team. That was my first gut reaction—which is fair, because you’re a busy person. I like to keep you very busy, and you don’t always have time to let me know what I should be paying attention to. So that was problem one.

Problem number two is, yes, you post things typically ahead of when they become more commonplace announcements. I saw a post this morning that I shared with you about MCP and agentic marketing processes, and how it’s going to replace your SEO if you’re doing traditional SEO. For some reason, that raised all of my insecurities and anxieties. Oh my gosh, I really am falling behind because I like to tell people about getting their foundation squared away. If I’m being really honest with myself, I think I focus on that because I feel so lost when I think about AI, agentic processes, MCP, N8N, and all these other things. So I’m like, let me focus on what I know best.

But I am now in the boat where I feel like my boat is trailing behind the giant AI yacht. I’m dog-paddling to try to keep up, and I’m just not there. So help me understand a couple of things. One, what is MCP? Two, we’ve talked about agentic AI, but let’s talk about agentic marketing processes. And three, how is someone who isn’t in the weeds with AI every day supposed to not sit at their desk and cry over all of this? Those are big questions, so maybe let’s take them one at a time. All right, let’s start with: What is MCP?

Christopher S. Penn – 02:36

Okay, MCP stands for Model Context Protocol. This is something initially advanced by Anthropic, the makers of Claude. It has since been adopted as a standard by OpenAI and now by Google. Sundar Pichai announced at Google Cloud Next last week that the Gemini family will adopt MCP. So what is this? It’s a way for a generative AI model to interface with other systems—a process called tool handling. MCP is a specific kind of tool. You create an MCP server that does stuff behind the scenes. It can be as simple as reading files from your disk or as complicated as using a bunch of SEO tools to optimize a page. It makes that keyword tool available in a tool like Claude Desktop.

You could call the tool something like “Make a Katie Joke.” That would be the tool name. You would build an MCP server that talks to an LLM to do all these things behind the scenes. But in Claude, it would just appear as a little tool icon. You’d say, “Hey, Claude, use the Make a Katie Joke tool to make a joke that Katie would make,” and it would talk to that MCP server and kick off all these processes behind the scenes. So think of MCP as a kind of natural language API where, in a conversation with ChatGPT or Claude, you’d say, “Hey, write me some Google Ads with the Google Ads tool.”

If you’ve built this tool for yourself or use one of the many free, open MCP servers available (which have data privacy issues), you can add new capabilities to generative AI that the tools don’t have on their own. The thing is, you still have to know what the tool does. You have to build it if it doesn’t exist, integrate it, and know when you should and shouldn’t use it. So as much as it may feel like you’re falling behind, believe it or not, your expertise is actually more important than ever for this. Even though we have MCP, N8N, and workflow automation, all that is software development. It still has to conform to the SDLC.

You may not write code, but you better know the SDLC, or you’re going to waste a lot of time.

Katie Robbert – 05:19

That’s helpful to know because, again, this may be—let me back up for a second. The information people share on social media is what they want you to see about them. They’re presenting their best selves. I understand that. I do that too as a representative of the company. That’s my job—to represent the best parts of what we do. And yet, my non-professional persona looks at what everyone else is sharing and thinks, Oh my gosh, I really am falling behind. And yet, here I am. My posts are right up there with the others. It’s like, no, I’m not. So I think that’s a little bit of the psychology of where a lot of people are feeling right now.

We’re trying our best to look like we know what we’re talking about, but on a daily basis, we’re like, I have no idea what’s happening. So that’s part one. Now I understand what an MCP is. In a nutshell, it’s kind of like a connector between two systems. The commercial version is Zapier—a lot of marketers use Zapier. It’s like, how do I get my data from this place to that place? It transfers information from one system to another.

Interestingly enough, I was at the animal shelter we work with yesterday, talking with the executive director. One of the problems she’s trying to solve is that she has literally hundreds of tabs in different spreadsheets of inventory at the shelter. They’re moving to a new shelter, and she’s trying to figure out where everything goes. I was describing to her a system—which doesn’t exist yet—that could include what you’re telling me is an MCP. In a very short version, I explained: We could take all your spreadsheets with all your tabs (which are basically your categories), put those into a database, and then layer generative AI on top of it with some system instructions.

Your staff takes a picture of whatever’s been donated. Generative AI recognizes, Okay, that’s two bags of dog food, one thing of wet food, and some pee pads. It looks like those go in Room 121 with the other things, and it adds to the database. I was explaining this process without knowing what that connector was going to be. I said, Let me go back and talk to Chris about it. But I’m fairly certain that’s a thing that can exist. So it sounds like I was describing something I didn’t have the terminology for.

Christopher S. Penn – 08:12

Exactly. Right now, here’s the thing—and this is something the LinkedIn hype crowd won’t tell you. As the average user, let me show you what the “getting started with MCP” quick start for non-technical users is. This is from Claude’s website:

For Claude Desktop users, get started using MCP in Claude Desktop. First, install Claude Desktop. Second, go into the config file and edit this JSON.

Katie Robbert – 08:41

You’ve already lost me.

Christopher S. Penn – 08:42

Exactly. Oh, by the way, you also need Node.js on your computer for this to run properly. So when someone says MCP is the future and it’s so easy—well, yes, if you’re a technical person, that’s true. If you’re a non-technical person, this is useless because you’re not going to sit there and install Node.js just to configure a pre-built MCP server.

You and your company—if you want to use these capabilities—need to have some IT resources because this is just straight-up IT. This isn’t even AI. This is just, Hey, you need these components in your kitchen before you can cook anything. As cool as MCP is (and believe me, it is very cool), it also has a very high technical bar of entry. So when you see somebody saying, Hey, this is the new AI-enabled MCP SEO, well, yes, that’s true. But what they’re not saying is, you’re probably not going to do this on your own if you’re a non-technical marketer.

It’s a business ploy to say, You should hire us as your SEO firm because we’re AI-enabled and we know how to install MCP services. Like, yeah, I can do that too. I just don’t advertise it because it’s kind of a jerk move.

Katie Robbert – 10:13

But I think that’s an important point to raise—not that you’re a jerk, but that a lot of us struggle with feeling like we’re not keeping up with AI because of these individuals—professionals, thought leaders, futurists, content creators—who put out this information: This is the future, this is how you’re going to do it. I can probably accurately describe agentic AI, but I couldn’t build it for you. And I think that’s where everyday marketers are struggling. Yeah, I think now I finally understand the concept, but I have no idea how to get started with the thing because there’s nothing out of the box for non-technical people.

It’s all still, to your point, a lot of software development, a lot of IT. Even if it’s just installing things so you can get to the drag-and-drop, asking people to suddenly update their config file is maybe one step beyond their technical comfort zone. I just—I know the purpose of this episode is to understand more about MCP and agentic marketing, but I’m struggling to feel like I’m keeping up with being able to execute on all these things that are happening. Because every day, it’s something new, right?

Christopher S. Penn – 11:54

So here’s how you get to MCP usage. First, you have to have the basics. Remember, we have the three layers we’ve talked about in the past:

Done by you—You’re copy-pasting prompts. There’s nothing wrong with that, but it’s labor-intensive. If you’ve got a great prompt and a way of doing things that works, you’re already ahead of 95% of the crowd who’s still typing one-sentence prompts into ChatGPT. That’s step one.

Done with you—How can you put that in some form of automation? We’ve talked about N8N in the past. I’ll give you an example: I put together a workflow for my newsletter where I say, Here’s my newsletter post. I want you to translate it into these four languages. It sends it to Google Gemini, then writes the updated versions back to my hard drive. This saves me about 20 minutes a week because I don’t have to copy-paste each prompt anymore. This is workflow automation.

Done for you (Agentic)—To turn this into an MCP server (which makes it an agent, where I’m not part of the process at all), I’d add the MCP server node. Instead of saying, When manual start (when Chris clicks go), you’d have an MCP server that says, When a generative AI tool like Claude requests this, run the process.

So, Claude would say, Hey, here’s this week’s newsletter—go make it. Claude Desktop would recognize there’s an Almost Timely Newsletter tool (an MCP server), send the request, the software would run, and when it’s done, it would send a message back to Claude saying, We’re done. That’s how MCP fits in. It takes the whole automation, puts it in a black box, and now it’s an agent.

But you cannot build the agent without the workflow automation, and you cannot build the workflow automation without the standard operating procedure. If you don’t have that fundamental in place, you’re going to create garbage.

Katie Robbert – 15:59

I think that’s also helpful because even just thinking about the step of translation—I’m assuming you didn’t just say, Hey, Gemini, translate this and accept whatever it gave back. You likely had to build system instructions that included, Translate it this way, then here’s how you’re going to double-check it, then here’s how you’re going to triple-check it. That to me is very helpful because you’re giving me confirmation that the foundational pieces still have to happen.

And I think that’s where a lot of these content creators on social platforms talking about MCP and agentic AI are skipping that part of the conversation. Because, as we’ve said before, it’s not the fun stuff—it’s not the push-the-buttons, twist-the-knob, get-the-shiny-object part. It’s how you actually get things to work correctly. And that’s where, as a regular human, I get caught up in the hype: Oh, but they’re making it look so easy. You just do the thing.

It’s like the people on social who post, Look how perfect my sourdough bread came out, but they’re not showing you the 17 loaves and five years of trial and error before this perfect loaf. Or they’re faking it with a mock background. I’m saying all this because I need that reminder—it’s all smoke and mirrors. There’s no shortcut for getting it done correctly.

So when I see posts about agentic marketing systems and SEO and email marketing—You’re not even going to have to participate, and it’s going to get it right—I need that reminder that it’s all smoke and mirrors. That’s my therapy session for the morning.

Christopher S. Penn – 18:33

And here’s the thing: If you have well-written standard operating procedures (SOPs) that are step-by-step, you can hand that to someone skilled at N8N to turn it into a workflow automation. But it has to be granular—Click here, then click here. That level of detail is so important. Once you have an SOP (your process), you turn it into workflow automation. Once the workflow automation works, you bolt on the MCP pieces, and now you have an agent.

But here’s the danger: All these things use APIs, and APIs cost either time, money, or resources. I’m using Gemini’s free version, which Google trains on. If I was doing this for a client, I’d use the paid version (which doesn’t train), and the bills start coming in. Every API call costs money.

If you don’t know what you’re doing and you haven’t perfected the process, you might end up with a five-figure server bill and wonder, What happened? Part of MCP construction and agentic AI is great development practices to make your code as efficient as possible. Otherwise, you’re going to burn a lot of money—and you may not even be cash-positive.

Katie Robbert – 21:27

But look how fast it is! Look how cool it is!

Christopher S. Penn – 21:36

It is cool.

Katie Robbert – 21:38

Going back to the original question about MCP—I read a post this morning about agentic marketing systems using MCP and how it’s going to change the way you do SEO. It said it’s going to optimize your content, optimize for competitors, find keywords—all of which sounds really cool. But the way it was presented was like, Oh, duh, why am I not already doing this?

I’m falling behind if I’m not letting the machines do my SEO for me and building these systems for my clients. This conversation has already made me feel better about where I am in terms of understanding and execution. Going back to—you still have to have those foundational pieces. Because agentic AI, MCPs, generative AI, shiny objects—it’s all just software development.

Christopher S. Penn – 22:59

Exactly. It’s all software development. We’ve just gotten used to writing in natural language instead of code. The challenge with shiny objects is that the people promoting them correctly say, This is what’s possible. But at a certain point, even with agentic AI and MCP automations, it’s more efficient to go back to classical programming.

N8N doesn’t scale as well as Python code. In the same way, a 3D printer is cool for making one thing at home, but if you want to make 10,000, classical injection molding is the way to go. New technology doesn’t solve old problems.

Katie Robbert – 23:47

And yet, it’s going to happen. Well, I know we’re wrapping up this episode. This has been incredibly helpful and educational for me because every week there’s a new term, a new thing we’re being asked to wrap our heads around. As long as we can keep going back to It’s just software development, you still need the foundation, then I think myself and a lot of other people at my skill level are going to be like, Whew, okay, I can still breathe this week. I don’t have to panic just yet.

Christopher S. Penn – 24:23

That said, at some point, we are going to have to make a training course on a system like N8N and workflow automation because it’s so valuable for the boring stuff—like keyword selection in SEO. Stay tuned for that.
