Microsoft Foundry plugin

Adds Microsoft Foundry model provider support to OpenClaw.

Distribution

• Package: @openclaw/microsoft-foundry
• Install route: included in OpenClaw

Surface

providers: microsoft-foundry; contracts: imageGenerationProviders

• Image-generation provider: microsoft-foundry

Requirements

• A Microsoft Foundry or Azure AI Foundry resource with deployments.
• API-key auth through AZURE_OPENAI_API_KEY or a configured provider API key.
• For Entra ID auth, install the Azure CLI and run az login before onboarding. OpenClaw refreshes Microsoft Foundry runtime tokens through az account get-access-token.

Chat models

Microsoft Foundry chat deployments use the provider model ref microsoft-foundry/<deployment-name>. Onboarding discovers Foundry resources and deployments with the Azure CLI, then writes the selected deployment name to the model config.

OpenClaw uses the Foundry /openai/v1 endpoint for supported OpenAI-compatible chat APIs:

• GPT, o*, computer-use-preview, and DeepSeek-V4 model families default to openai-responses.
• MAI-DS-R1 and other chat-completion deployments use openai-completions unless an explicit supported API is configured.
• MAI-DS-R1 is recorded as reasoning-capable through reasoning content, not through reasoning_effort. Its context and output token metadata are 163,840 tokens.

Anthropic Claude deployments in Microsoft Foundry use the Anthropic Messages API shape, not the OpenAI-compatible /openai/v1 shape. Configure those as a custom anthropic-messages provider until the Microsoft Foundry plugin grows a native Anthropic runtime. When the Foundry deployment name differs from the Claude model ID, set params.canonicalModelId on the model entry so OpenClaw can apply model-specific wire contracts, map /think off correctly, and preserve signed thinking safely.

MAI image generation

The plugin registers microsoft-foundry for image_generate with the current Microsoft AI image models:

• MAI-Image-2.5-Flash
• MAI-Image-2.5
• MAI-Image-2e
• MAI-Image-2

Use a deployed MAI image deployment name as the model ref. The provider does not declare a default image model because the MAI API requires your deployment name in the request model field:

{  agents: {    defaults: {      imageGenerationModel: {        primary: "microsoft-foundry/<deployment-name>",        timeoutMs: 600000,      },    },  },}

Prompt-only generation calls Microsoft Foundry's MAI generations endpoint: /mai/v1/images/generations. Reference-image edits call /mai/v1/images/edits and are limited to MAI-Image-2.5-Flash and MAI-Image-2.5 deployments.

Prompt-only generation can use a custom deployment name with just the Foundry endpoint configured. For image edits with a custom deployment name, select the deployment through onboarding or include model metadata so OpenClaw can verify that the deployment is backed by MAI-Image-2.5-Flash or MAI-Image-2.5.

MAI image constraints:

• Output: one PNG image per request.
• Size: default 1024x1024; both width and height must be at least 768 px.
• Total pixels: width × height must be at most 1,048,576.
• Edits: one PNG or JPEG input image.
• Unsupported shared hints such as aspectRatio, resolution, quality, background, and non-PNG outputFormat are not sent to Microsoft Foundry.

Troubleshooting

• az: command not found: install the Azure CLI or use API-key auth.
• Microsoft Foundry endpoint missing for MAI image generation: select a Foundry deployment through onboarding or add models.providers.microsoft-foundry.baseUrl.
• supports MAI image deployments only: the selected image model points at a non-MAI deployment. Use a deployed MAI image model for image_generate.
