We gave an AI agent a systeme.io MCP key on a free account. It built an email-capture funnel in about 100 seconds, then an automation rule in 82 seconds on the second round. The free plan refused the next rule, and our first test sign-up got no welcome email, while the second one did. We ran the test on November 13, 2026 with Claude Code on a free systeme.io account, no credit card.
This is a test of what an agent actually gets for free, not a tutorial on MCP. Every number below comes from our own run. How we test explains why our agents, not a person, do the testing.
What is the systeme.io MCP server?
It’s a server that lets an AI agent drive your systeme.io account through a set of tools. MCP (Model Context Protocol) is the open standard for plugging tools into an agent, described on modelcontextprotocol.io. Systeme.io runs its own server, and it’s in the free plan.
The key is created in Settings > Connections > MCP & API keys. You name it, set an expiry date, and you can hold two. The key goes into the server address (https://mcp.systeme.io/mcp?mcpKey=YOUR_KEY), which you add to your agent. Ours was Claude Code.
We asked the server what it offers: initialize answered “Systeme.io MCP server” version 0.1.0, and tools/list returned 171 tools. Contacts, tags, funnels and their pages, automation rules, emails, newsletters, campaigns, courses, products, coupons, calendar, communities, SMS. Treat the key like a password: whoever holds it controls the account.
Round one: how fast can an agent build a funnel?
About 100 seconds for a funnel with two pages. Our prompt asked for an email-capture funnel for a free checklist called “AI automation checklist”: an opt-in page, a thank-you page and real copy. The run lasted 179 seconds in total and made 26 MCP calls, the account having no funnel at the start.
At the end the dashboard showed a funnel with two steps and a live opt-in page: a headline, a generated image, a first-name-and-email form and a button. We read the public page like a visitor would. Three things were wrong:
- the testimonial had its name in brackets:
[Customer name],[Brand]; - the video block was empty;
- the thank-you page said the checklist was on its way from
[Your name].
The agent wrote the copy and left the placeholders the template gave it. If you let an agent build a page, plan a read-through before it goes public.
What happens when the agent tries to send an email?
The server refused: “This email address must be verified and eligible for use as a marketing sender”. Our address showed as Verified in Settings > Emails, with a warning: to send from it, you must authenticate its domain.
Systeme.io’s guide to authenticating a domain says it’s mandatory to send emails, and that you must contact support after adding the records. We added the three CNAME records it asks for. The support form has a captcha, and our agents never solve those, so we stopped there. The status stayed on “Pending” at first. Without a verified sender, the agent couldn’t create the welcome email, and so couldn’t create the rule that needs it.
Round two: an email and an automation rule in 82 seconds
Same account, a new prompt: 18 calls, 82 seconds. We asked for the welcome email from our own address, then a rule sending it when someone subscribes through the funnel’s form, then a second rule. This time the server accepted our sender address.
The first rule went live: trigger “form subscribed”, action “send email”. The second was refused with the exact message “Automation rules limit reached”. The pricing page says it plainly: the free plan includes 1 rule.
Did the welcome email arrive?
The first time, no. The second time, yes. We opened the live page, typed a first name and a test address, and clicked. The thank-you page opened. Then we waited for the welcome email: nothing in the inbox, nothing in spam.
We can’t prove why. About forty minutes later, Settings showed our domain as Verified, and we had never contacted support. We signed up again with a new address, and the email arrived in under a minute. Gmail’s headers show it was signed with our own domain (DKIM pass). Our best guess is that the domain was not verified yet at the first sign-up. If you want emails to leave, do the domain step first.
What does the free plan give you?
Here’s the list as we tested it, with limits read on the pricing page on November 13, 2026:
| Free plan, as tested | |
|---|---|
| MCP key | Yes, up to 2, no card |
| Funnel from a prompt | Yes, about 100 s for 2 pages |
| Automation rules | 1 (the second is refused) |
| Funnels / contacts | 3 / 2,000 |
| Email campaigns | 1 |
| API rate | 30 requests per minute |
| Sending email | Works once the domain is authenticated (blocked for us until then) |
| Next plan | Startup, $17 per month |
Our verdict
It’s a fast way to get a first funnel on screen, and it’s free to try. But it’s a draft, not a launch. The agent did what we asked in under two minutes per round. Everything it got wrong was either a template leftover (placeholders) or a platform step it can’t do alone (authenticating a domain).
So the order we’d follow: authenticate your domain first, then let the agent build, then read every line. The free plan we used is the one behind our systeme.io link. For other agent-driven builds, see our landing page in 24 hours with Astro and Cloudflare and our daily agent, Hermes. If you’re choosing an automation tool instead, Zapier alternatives compared has the same kind of test.
FAQ
Is the systeme.io MCP server included in the free plan?
Yes. On November 13, 2026, we created an MCP key on a free account, with no credit card. Settings > Connections > MCP & API keys lets you create up to 2 keys, each with a name and an expiry date. The server listed 171 tools, version 0.1.0.
What can an AI agent do with the systeme.io MCP server?
In our test, Claude Code created a funnel, an opt-in page, a thank-you page, a welcome email and an automation rule that sends the email when the form is submitted. The 171 tools also cover contacts, tags, courses, products, coupons, newsletters and SMS. We did not test those.
What are the limits of the systeme.io free plan?
Pricing page, November 13, 2026: 3 funnels, 1 automation rule, 1 email campaign, 2,000 contacts, 1 blog, 1 course and API calls limited to 30 per minute. The free plan never expires. In our test, a second rule was refused with 'Automation rules limit reached'.
Did our systeme.io welcome email arrive?
Not the first time. Our first test sign-up, around 10:30, got no email in the inbox or spam. About forty minutes later, with the domain showing as Verified in Settings, a second sign-up got the email in under a minute, signed with our own domain (DKIM pass). We can't prove the domain was the cause, but the help guide says domain authentication is mandatory to send.
Do you have to fix what the agent writes?
Yes. The pages the agent built still had template placeholders: a testimonial with its name in square brackets, an empty video block and '[Your name]' on the thank-you page. Read every line before publishing.
