Kit (formerly ConvertKit) vs OpnForm: at a glance
What is Kit (formerly ConvertKit)?
Kit handed page-building to an agent, then went back to cleaning up the subscribers list
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
What is OpnForm?
OpnForm added a full MCP server in v2.4 — AI assistants can now build, preview, and manage forms without touching the UI.
OpnForm shipped its MCP server in v2.4 (August 2026) and spent v2.5 hardening the guest-first flow: forms can now be built from Claude, Cursor, ChatGPT, or Codex without an account, with read-only previews before any data is saved. The official OpenAI plugin is distributed and verified. v2.3 added Make/Albato integrations, AI formula generation for computed variables, and an audio form block. The product has moved from a self-hosted form tool to a tool explicitly designed for AI agent workflows.

Kit handed page-building to an agent, then went back to cleaning up the subscribers list
◆ Current state
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
◆ Where it's heading
The Kit MCP is the axis, and it has already made its jump — from read-and-analyze in May to producing the published artifact in July. What follows is consolidation: the manual surfaces are being tidied so the things an agent can do and the things a creator does by hand sit on comparable footing. Nothing in this window extends the MCP itself, which makes the current period a pause rather than a redirection.
◆ Prediction
Expect the MCP surface to extend to more of the artifacts Kit publishes now that landing pages have proven the pattern. The subscriber-page work reads as a finished cleanup rather than the start of a larger rebuild.
OpnForm
6.3MKT AUTO
OpnForm added a full MCP server in v2.4 — AI assistants can now build, preview, and manage forms without touching the UI.
◆ Current state
OpnForm shipped its MCP server in v2.4 (August 2026) and spent v2.5 hardening the guest-first flow: forms can now be built from Claude, Cursor, ChatGPT, or Codex without an account, with read-only previews before any data is saved. The official OpenAI plugin is distributed and verified. v2.3 added Make/Albato integrations, AI formula generation for computed variables, and an audio form block. The product has moved from a self-hosted form tool to a tool explicitly designed for AI agent workflows.
◆ Where it's heading
The MCP investment is the clearest strategic signal in OpnForm's recent history: two consecutive major releases have been organized around making forms AI-native — first adding the server, then hardening the security and guest-first creation flow. Computed variables gaining PDF support and AI formula generation in the same cycle completes a workflow where an AI agent can construct a form, define computed logic, and generate a submission PDF without human intervention.
◆ Prediction
The next focus will be MCP submission handling — an AI agent that can build a form should also be able to query and act on its submission data. v2.4 added submission reading via MCP; expect richer filtering, aggregations, and webhook-triggered agent actions in the next release.
