Integrations
Compatibility has several layers. Detecting a provider does not automatically make its workflows public or safe to execute.
This matrix covers Core 0.3.55. Download it from the official WordPress.org listing.
Product surfaces
| Surface | Current scope | Control boundary |
|---|---|---|
| Content | Posts, navigation, search, taxonomies, site information, and public discovery. | Read-only Standard Tools form the default baseline. |
| Forms | Provider-aware discovery, reviewed browser preparation, and reviewed publication for Contact Form 7 and WPForms Lite. | Every form is reviewed separately. Preparation fills the visible form but leaves submission to the visitor. Agent-executed submission is separately enabled, requires approval, and cannot be undone. |
| Commerce | WooCommerce product discovery, comparison, cart inspection, and selected cart changes. | Cart writes require approval. Checkout, payment, orders, authentication, and accounts are excluded. |
Forms compatibility matrix
This table reflects the provider support in Core 0.3.55. Tested support still has per-form enablement, field, workflow, and approval boundaries.

Fill a form without submitting it
Form preparation lets compatible WebMCP browser agents fill exact, owner-reviewed WPForms Lite and Contact Form 7 forms on selected published pages. The visitor reviews or edits the answers and uses the form's normal Send or Submit button. This is separate from agent-executed submission and does not require transactional tools or the Assistant add-on. Preparation supports only these two providers.
Native-browser checks covered WPForms Lite 2.0.1.1 and Contact Form 7 6.1.7. This does not establish support for every version, field type, form configuration, or browser assistant. Follow the short form preparation setup guide.
What agent-executed form submission means
Eligible tools are registered per form, not per provider. An administrator must enable form submission and opt in to the exact reviewed form. Immediately before an irreversible submission, the visitor sees the provider, exact field values, and disclosed side effects, then explicitly approves or cancels.
Provider validation and confirmation remain authoritative. Notifications, redirects, conditional logic, honeypots, and third-party feeds remain provider-controlled and must be reviewed before a form is enabled. Unsupported or high-impact fields cause the form tool to remain unavailable.
WooCommerce boundary
Read-only product search, product lookup, and categories are part of Standard Tools when WooCommerce is active. Core 0.3.55 has been tested with WooCommerce 10.5.1 and 10.9.4 for discovery, public availability, cart inspection, and the supported cart tools. Separately reviewed transactional tools can inspect and change the visitor's cart with approval and idempotency controls. Open for Agents does not implement checkout, payment, order placement, login, registration, profile, or account-changing tools.
