Google Antigravity

PlannedLast tested: August 31, 2026

Google Antigravity is an agentic development environment that can connect to MCP servers and use their tools during research and coding workflows.

Public OAuth endpoint

Connect Glushkov Modelling MCP

Add this public endpoint in the MCP, connectors, apps, or integrations section of Google Antigravity, then complete OAuth authorization when prompted.

https://mcp.glushkov-modelling.com/mcp-oauth

Do not use https://mcp.glushkov-modelling.com/mcp. It is a legacy endpoint and is not intended for public OAuth connections.

Step by step

Connect Google Antigravity to the archive

Follow the steps in order. Interface labels can change over time, but the public OAuth endpoint remains the same.

01
Open MCP configuration
Open Antigravity MCP settings and choose the option to open or edit the raw MCP configuration. If the application does not offer this option, open the global configuration file manually.
```
                                                            ~/.gemini/antigravity/mcp_config.json
                                                        
```
Note: Some versions or integrations may use a workspace-level file such as .agents/mcp_config.json. Follow the path shown by your Antigravity installation when it differs.

Add the server

Add Glushkov Modelling MCP to the mcpServers object.

                                                            json
{
 "mcpServers": {
 "glushkov-modelling": {
 "serverUrl": "https://mcp.glushkov-modelling.com/mcp-oauth"
 }
 }
}

Note: If the file already contains other MCP servers, add this entry inside the existing mcpServers object and preserve valid JSON. Do not add a client secret, API key, or Keycloak URL.

03
Save and refresh
Save the MCP configuration, return to Antigravity, and refresh or reload the MCP server list.
Note: The UI label may be Refresh, Reload, Manage MCP Servers, or similar.
04
Authenticate the server
Select Glushkov Modelling MCP and choose Authenticate or Connect. Complete sign-in or registration in the browser window opened by Antigravity.
Note: Allow popup windows and cookies. Confirm your email if this is the first connection. The public flow does not require an API key.
05
Confirm tool availability
Return to Antigravity and confirm that the server status is connected and that its tools are available to your agent or chat session.
Note: Start a new chat or agent session if the tool list does not refresh immediately.

Test the connection

Send the test prompt and confirm that the answer uses the Glushkov Modelling archive and provides source links.

                                                            Use Glushkov Modelling MCP. Find material about Le Requin 1750 and list the hull construction stages with links to the original archive pages.

Note: If the MCP tools do not appear after authentication, restart the session and check the MCP server status.

Test the connection

Ask your first archive question

Once the MCP tools are connected, send this prompt in a new Google Antigravity conversation.
