Installation

Our standard Docker images already include this plugin. If you use a -slim image or another setup, install it with the following command: 

kestractl plugins get io.kestra.plugin:plugin-ai --compatible-for $KESTRA_VERSION

For kestractl, use your Kestra version with --compatible-for, or specify an exact plugin version.

For Kestra CLI, replace LATEST with a specific version or version range to pin the plugin version.

Properties

API Key

Mistral AI API key used to authenticate requests. Store it as a Kestra secret rather than inline. No default: this property is required.

Base URL

Custom base URL overriding the provider's default endpoint. Useful for enterprise gateways, proxies, self-hosted deployments, or test doubles such as WireMock. Defaults to the provider's public endpoint.

CA PEM certificate content

PEM-encoded certificate authority chain, as text, used to verify the TLS certificate presented by a custom endpoint. Not set by default, in which case the JVM's default trust store is used.

Client PEM certificate content

PEM-encoded client certificate and private key, as text, used for mutual-TLS authentication against enterprise AI endpoints. Not set by default, in which case the default HTTP client is used.
