Kit (formerly ConvertKit) vs Formidable Forms: at a glance
What is Kit (formerly ConvertKit)?
Kit rebuilt its landing page editor, then handed the controls to an AI agent.
Kit's recent releases converge on one thing: giving creators a full publishing surface inside Kit rather than sending them to a third-party page builder. The landing page editor was rebuilt in June with 20+ templates and full control over layout, fonts and sections; custom favicons and the Creator profile to Newsletter site rename finished the job of making those pages feel owned rather than hosted. The newest release lets the Kit MCP build and edit those pages directly. Alongside runs an audience-intelligence thread - Subscriber Signals in early access - and network features letting creators request connections with each other.
What is Formidable Forms?
Formidable widens MCP compatibility and locks down signature files
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.

◆ Current state
Kit's recent releases converge on one thing: giving creators a full publishing surface inside Kit rather than sending them to a third-party page builder. The landing page editor was rebuilt in June with 20+ templates and full control over layout, fonts and sections; custom favicons and the Creator profile to Newsletter site rename finished the job of making those pages feel owned rather than hosted. The newest release lets the Kit MCP build and edit those pages directly. Alongside runs an audience-intelligence thread - Subscriber Signals in early access - and network features letting creators request connections with each other.
◆ Where it's heading
The Kit MCP is the axis. It arrived in May as a read-and-analyze tool - ask questions about your list, create tags or broadcasts from Claude, ChatGPT or Cursor - and has now crossed into building the actual published artifact. That sequencing is deliberate: rebuild the editor as a structured, template-driven system first, then expose it to an agent, because an agent can only assemble a page that is composed of describable parts. The rename and favicon work point the same way, toward Kit as the place a creator's web presence lives rather than just where email is sent.
◆ Prediction
Expect the MCP surface to extend from landing pages into sequences and the newsletter site itself, and Subscriber Signals to move out of early access as the data layer the agent reasons over.
Formidable Forms
6.3MKT AUTO
Formidable widens MCP compatibility and locks down signature files
◆ Current state
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.
◆ Where it's heading
Two threads are running in parallel across the add-on family. One is agent access, opened by the Forms API v2.0 MCP adapter and the WordPress Abilities API, now being made to coexist with the other plugins already shipping MCP adapters on the same site. The other is a sustained security pass, visible in signature file handling, tokenized CSV downloads, and the Stripe and core-plugin hardening earlier in the window.
◆ Prediction
Adapter-version collisions between plugins are likely to recur as more WordPress plugins ship MCP servers, so expect further compatibility patches rather than new API surface in the near term.
