Stitch MCP installation in Antigravity

Google Antigravity
1

Has anyone managed to install this MCP? Can’t find it in MCP store so manual install necessary but I’m not having any luck in my stitch json in mcp_config.json
Anybody successfully installed this MCP?

I sorted it with the help of ChatGPT 5.2 (Gemini 3 pro was useless in helping).
If anyone is interested this was the entry needed in mcp_config.json
“stitch”: {
“command”: “/home/jkenny/.local/bin/stitch-mcp-proxy.sh”,
“args”:
}

And that executable script contents
set -euo pipefail

export HOME=“/home/jkenny”
export PATH=“/usr/local/bin:/usr/bin:/bin”
export STITCH_PROJECT_ID=“DJ-Collection”

Force Google ADC discovery

export CLOUDSDK_CONFIG=“/home/yourname/.config/gcloud”
export GOOGLE_APPLICATION_CREDENTIALS=“/home/yourname/.config/gcloud/application_default_credentials.json”

Pinned to published npm version

exec /usr/local/bin/npx -y “@_davideast/stitch-mcp@0.0.5” proxy

Haven’t tested it or used it yet but it no longer throws an error in MCP servers

I sent a feature request through the built-in Antigravity feedback form to have the Google Stitch MCP added to the MCP Store. You may want to do the same.

Yea, that script didn’t work but after a lot of gcloud auth & running npx add-skill google-labs-code/stitch-skills --list & help from ChatGpt, I finally got it working & it redesigned a landing page for me - pretty impressed
