Formidable Forms vs Senja: at a glance
What is Formidable Forms?
The forms plugin just opened its data to AI agents through an MCP adapter.
Formidable Forms ships as a core plugin plus a fleet of separately versioned add-ons — PDFs, Visual Views, Digital Signature, Export View, Forms API — each getting its own small release. Most of that stream is bug fixes and hardening, including two security passes in the last month credited in part to Wordfence. The exception is Forms API v2.0, which adds support for the WordPress Abilities API and an MCP adapter alongside tighter API key validation.
What is Senja?
Senja is closing the loop from collecting proof to producing the asset.
The dated window covers the merge of classic forms into forms 2.0, native Slack notifications, and an MCP server that connects Senja directly to an assistant. The undated rows fill in both ends of the story: a 2025 run that added AI sizzle reels, case studies from single testimonials, editable testimonial images and reusable video clips, and a 2026 run concentrated almost entirely on invites — performance tracking, editable follow-ups, quick invite, and Stripe events triggering the ask.

Formidable Forms

The forms plugin just opened its data to AI agents through an MCP adapter.
◆ Current state
Formidable Forms ships as a core plugin plus a fleet of separately versioned add-ons — PDFs, Visual Views, Digital Signature, Export View, Forms API — each getting its own small release. Most of that stream is bug fixes and hardening, including two security passes in the last month credited in part to Wordfence. The exception is Forms API v2.0, which adds support for the WordPress Abilities API and an MCP adapter alongside tighter API key validation.
◆ Where it's heading
Two threads are running at once. The first is a security tightening pass across the add-ons: constant-time API key comparison, restrictions on where a key can be used, and validation that signature deletion only touches signature files on the active entry. The second, newer thread is making form data reachable by software rather than only by humans — the gated-content actions added to PDFs and Visual Views, and now an MCP adapter on the API. The add-ons are converging on a shared access-control model rather than each solving it locally.
◆ Prediction
Expect the MCP surface to widen from the API add-on into the entry and view add-ons, since those already gained gated-content actions and hold the data an agent would want to read.
Senja
0.0MKT AUTO
Senja is closing the loop from collecting proof to producing the asset.
◆ Current state
The dated window covers the merge of classic forms into forms 2.0, native Slack notifications, and an MCP server that connects Senja directly to an assistant. The undated rows fill in both ends of the story: a 2025 run that added AI sizzle reels, case studies from single testimonials, editable testimonial images and reusable video clips, and a 2026 run concentrated almost entirely on invites — performance tracking, editable follow-ups, quick invite, and Stripe events triggering the ask.
◆ Where it's heading
Senja is building a pipeline rather than a widget. Collection is being automated and measured, the library is being turned into finished formats — reels, case studies, clips — and the MCP server exposes the whole thing to an assistant that can query it. The 2026 releases suggest the constraint they are working on now is volume at the top of the funnel, since every downstream format is only as good as the proof coming in.
◆ Prediction
With invites instrumented, the next obvious step is acting on the numbers — timing or targeting invites automatically off the tracking data, rather than adding more places to send them from.
