How to auto-approve specific local MCP tools (bypass “Accept” prompt) in Antigravity?

Hello,

I’m using the Antigravity extension and I’ve configured a local custom MCP server via mcp_config.json to handle background logging tasks. My MCP server exposes a tool called log_interaction which the agent uses frequently.

Currently, every single time the agent tries to use this tool, the extension interrupts the workflow and prompts me to click “Accept” or “Reject”. This makes autonomous background workflows impossible.

I tried adding the "alwaysAllow": ["log_interaction"] property to my server’s configuration block inside mcp_config.json (similar to how other extensions like Roo/Cline handle it), but the extension ignores it and still prompts me for confirmation on every turn.

Is there a hidden VSCode setting, a specific JSON schema property, or an “Allow List” feature specifically for MCP tools in Antigravity to silently auto-approve trusted ones?
If not, is this planned for a future release? It would greatly improve the agent’s autonomy for safe local tasks.

Thank you!
