Claude Model Provider Extension for VS Code

This Visual Studio Code extension contributes language models that can be used in the chat view and also by other extensions that allow selecting language models.

Why?

Adding your Anthropic API key directly in Visual Studio Code only allows using Claude models from the Chat sidebar. Trying to use the models from another extension will produce system: text content blocks must be non-empty errors.

This extension allows using Claude models from other extensions as well.

Use in Chat

By default, extension-provided language models are not visible in the chat model picker. Use the Chat: Manage Language Models command to list all models, and toggle visibility for the model(s) you want. Afterwards, the models should be available in Ask mode.

Setup

The extension will prompt you to enter your API key when you first use it. It's recommended to generate a new key from the Claude Console.
