Zactonz AI Connector for Mistral AI

Description

This plugin by Zactonz Technologies adds Mistral AI as an AI provider for the WordPress AI Client. It is built for the WordPress Settings > Connectors screen and for the plugin directory connector search, so a site owner who needs Mistral AI can find it, install it, paste a key, and have every AI feature in WordPress start using it.

Mistral AI publishes European open-weight and commercial models, hosts a few third-party ones alongside them, and reports per-model capabilities in its own API. This connector reads those capability flags directly, so chat, vision, function calling and reasoning each appear in WordPress with exactly the features Mistral says they have. Its embedding models are recognised as well, and will be offered as soon as the WordPress AI Client ships its embedding model contract. Transcription, speech, OCR, moderation and safety classification models are listed by the same endpoint and are left out, because the AI Client has nowhere to put them.

• Vision input on models that accept images
• Tool calling on models that report function support
• Structured output with a JSON schema on models that support it
• Single and batch embedding generation, offered once the WordPress AI Client ships its embedding model contract
• Reasoning effort control for the default text model
• Cancellable server-sent event streaming for content, reasoning, and tool-call chunks
• Configurable request timeouts for text and embeddings
• API key supplied by a PHP constant or an environment variable instead of the database
• An API base URL override for a proxy or gateway, within the hosts and ports WordPress permits outbound requests to
• Redacted diagnostics and a WordPress Site Health connectivity test

External services

This plugin sends requests to Mistral AI, a third-party service, and does nothing without it. Requests go to the Mistral AI API at https://api.mistral.ai/v1, or to the API base URL you set in the connector settings.

What is sent and when: the API key you configure, and the prompts, images, tool definitions and generation settings that a WordPress AI feature passes to the AI Client, each time such a feature runs a request through this connector. The connector also requests the model catalogue when its settings screen loads, when a WordPress AI feature asks which models are available, and when you run diagnostics or the Site Health test. No other data is sent.
