Description
ModelGain WebMCP Forms provides a fail-closed, explicit WebMCP contract for Contact Form 7. Site administrators choose individual compatible forms in Tools > WebMCP Forms. New and undiscovered forms are disabled by default.
An enabled tool fills only supported human-visible fields for review. It never submits a form, calls submit() or requestSubmit(), bypasses Contact Form 7 validation, or bypasses CAPTCHA, spam protection, nonce/CSRF behavior, or submission hooks. The ordinary Contact Form 7 human flow remains authoritative.
The initial release supports text, email, URL, telephone, number, date, textarea, select, and radio fields. File uploads, checkboxes, acceptance, quizzes, CAPTCHA/anti-spam controls, provider-internal hidden inputs, sensitive names, multiple selects, and unknown controls fail closed.
WebMCP is treated as progressive enhancement. Sites and human forms continue to work when the browser does not implement document.modelContext. This plugin exposes a structured browser tool surface; it does not provide or bundle an AI agent.
Browser support
WebMCP is an emerging browser API. Agent tools are registered only when the browser exposes the supported document.modelContext.registerTool() interface in a secure context. On unsupported browsers, the plugin leaves the normal Contact Form 7 experience unchanged.
Privacy and external services
This plugin makes no external requests, includes no telemetry, and sends no form data to a cloud service. Frontend configuration contains only the enabled form ID, resolved tool name, description, and explicit supported-field JSON Schema.
Installation
- Install and activate Contact Form 7.
