AI Relay for VS Code

Claude, Gemini and Microsoft Copilot as coding agents over your project — one chat panel, your own accounts, pick the agent from a dropdown.

Agent	Signs in with
Claude	the Claude Code CLI you are already logged in to
Gemini	a Gemini API key, Vertex AI (gcloud), or a Vertex deployment behind Apigee
Copilot	your signed-in Microsoft Copilot web session (SSO and all)

The agents read, search, edit and run commands across the whole workspace; every tool call streams into the transcript, and you choose whether each one asks first, whether file edits are applied silently, or whether everything just runs.

Setup

Install the airelay command — the extension is a front-end for it and needs it on your machine. No Java required; see Install: curl -fsSL https://raw.githubusercontent.com/Chelayel/ai-relay/main/packaging/install.sh | sh on macOS/Linux, irm …/install.ps1 | iex on Windows, or an installer from the releases page. If it isn't on your PATH, set airelay.path.
Claude needs nothing more. For Gemini, Copilot or web search, run AI Relay: Set Up an Agent (command palette, or the ⚙ button in the panel): pick the connection, answer a few input boxes — keys are masked — and it is saved to ~/.airelay/config.properties, readable only by you and shared with the command line and the IntelliJ plugin. Copilot's default is browser mode: a Chrome/Edge tab opens on the first turn and you sign in there.
Open the AI Relay view in the activity bar.

Using it

Enter sends, Shift+Enter adds a line, Esc stops a running turn.
The chip under the message box shows the current file, or the selected lines when there is a selection, and follows the editor as you move around. It is attached to the next message; click it to leave it out.
The permission bar appears when the agent wants to run something in ask mode; Allow runs it once, Always for the rest of the conversation.
New starts a fresh conversation; switching agent or permission mode does too.

Settings

Setting	Default
