Strata19 for Antigravity

Free Local

Antigravity receives a host-native Strata19 plugin: the local MCP server, project skills, and lifecycle hooks. The installer copies the bundle, preserves your other MCP servers, refreshes the running host, and refuses to report success until Antigravity accepts every advertised tool.

Delivery: Host-native plugin and self-verifying installer
Experience: Antigravity IDE tools, skills, and lifecycle hooks

Install and connect

Step 1

Get the release source

Clone the repository if it is not already present. The installer copies only the packaged Strata19 bundle into Antigravity’s plugin directory.

git clone https://github.com/jordanallen87/praetor.git
cd praetor

Step 2

Run the self-verifying installer

The installer merges the Strata19 server into Antigravity’s global MCP configuration without replacing unrelated servers.

node scripts/strata19/host/install-antigravity-plugin.mjs

Step 3

Open your repository

Start Antigravity in the project you want Strata19 to inspect, then ask the agent to initialize that repository.

Verify the connection

If Antigravity was not running during installation, start it and rerun the installer in verification-only mode. A successful check reports the host status, accepted tool count, zero tool errors, and an explicit OK line.

node scripts/strata19/host/install-antigravity-plugin.mjs --verify-only

Know the boundary

• Antigravity does not start a plugin-declared MCP server reliably from the plugin folder alone; the installer also registers the server in the global MCP configuration.
• The host has no plugin filesystem watcher. A running instance must be refreshed by the installer before the new bundle is visible.
• The code index, specbook generation, local workflow execution, and verification cells are certified. Visual workspace behavior is not claimed here.
