Kit MCP for AI Agents. Manage audience data and campaign metrics in conversation.

Kit (ConvertKit) connects your AI agent directly to your email marketing platform. Use this MCP to manage subscribers, track audience tags, and analyze broadcast campaign performance without ever opening a dashboard.

The pain of logging into multiple marketing dashboards. Solved with Vinkius AI Gateway

Today, if you want to know the performance of your last email blast, you're stuck. You have to log into Kit, find the specific campaign, navigate through different tabs for open rates, then click another tab to see unique clicks. If you need to segment users who opened but didn't click, you're looking at a minimum of five separate screens and several hours of manual cross-referencing.

With this MCP, all that complexity disappears. You simply ask your agent: 'What was the CTR for my last broadcast?' The data comes back directly in text format. Your AI client handles the dashboard navigation behind the scenes, giving you an immediate answer without a single copy/paste.

Manage audience segmentation with Kit (ConvertKit) MCP

Manually updating user tags is tedious. You might find a new lead who needs to be marked 'Podcast Listener' or 'Ebook Downloaded,' which requires logging in and clicking through settings just to apply a simple marker.

Now, you tell your agent: 'Apply the Podcast Listener tag to john.doe@example.com.' The action happens instantly through the MCP, updating the record and ensuring that user is properly segmented for future campaigns.

What your AI can actually do with this

This MCP lets you manage your entire subscriber lifecycle from within your AI client. Instead of juggling dashboards and exporting spreadsheets to figure out who opened an email or what group a lead belongs to, your agent does the heavy lifting for you. You can ask it to pull open rates and click-through metrics from your most recent broadcast campaign instantly.

Need to clean up your list? Your agent can look up specific users by ID, check their current tags, or even apply new segmentation markers based on a conversation. It also manages all your forms and automated email sequences, making sure every lead gets the right follow-up message automatically. Connecting this MCP via Vinkius means you get instant access to these core marketing functions from any compatible AI client, letting you focus on content strategy instead of data retrieval.
