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 OpnForm?

OpnForm is turning its V2 platform into an automation surface, one integration at a time.

OpnForm shipped V2 in June — a major release that added PDF generation, computed variables, form import from Typeform, Tally, Google Forms and Fillout, and a Free/Pro/Business/Enterprise plan system with self-hosted license gating. The three releases since have been almost entirely self-hosting repair: OIDC sign-in recovery, trusted-proxy handling, PDF template editors breaking under relative API paths. v2.3.0 is the first post-V2 release that adds capability rather than fixing it.

Formidable Forms vs OpnForm: editorial side-by-side

F6.3

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.

OpnForm
MKT AUTO
5.0

OpnForm is turning its V2 platform into an automation surface, one integration at a time.

◆ Current state

OpnForm shipped V2 in June — a major release that added PDF generation, computed variables, form import from Typeform, Tally, Google Forms and Fillout, and a Free/Pro/Business/Enterprise plan system with self-hosted license gating. The three releases since have been almost entirely self-hosting repair: OIDC sign-in recovery, trusted-proxy handling, PDF template editors breaking under relative API paths. v2.3.0 is the first post-V2 release that adds capability rather than fixing it.

◆ Where it's heading

The pattern is a large platform release followed by a long tail of self-hosted fixes, and OpnForm is now coming out the other side. v2.3.0 layers automation onto the V2 foundation — Make and Albato integrations, AI-assisted formula generation for the computed variables V2 introduced, and an audio block — while still closing self-hosted PDF bugs. Feature gating is doing real work now: Custom Code and similar capabilities are tied to license entitlements, with migrations backfilling existing self-hosted records.

◆ Prediction

Expect more integration connectors and further AI assistance layered onto computed variables, since both extend V2 primitives rather than requiring new ones. The self-hosted PDF editor has needed fixes in three consecutive releases, so another round there is likely.
