Add SeekOut MCP to Google Antigravity’s IDE and CLI with the shared MCP configuration and SeekOut sign-in.
Antigravity is Google’s agent-first development environment. It connects to SeekOut MCP directly over Streamable HTTP and signs each user in with their own SeekOut account, so no administrator provisioning is required.The Antigravity IDE and CLI share one MCP configuration file. Adding SeekOut once makes it available in both.
This page covers the Antigravity IDE and CLI. Gemini Enterprise is a separate product with a different setup — see Gemini Enterprise.
Open Settings (Cmd+, on macOS, Ctrl+, on Windows and Linux) and select the Customizations tab. Scroll to Installed MCP Servers.In the Antigravity IDE you can also click the … menu at the top of the agent side panel and select MCP Servers.

Open the MCP configuration
Click Open MCP Config to edit mcp_config.json.Add MCP + opens Antigravity’s server catalog. SeekOut isn’t listed there, so add it through the configuration file.
3
Add the SeekOut server
Add the seekout entry inside mcpServers, keeping any servers you already have:
Click the refresh icon next to Installed MCP Servers. SeekOut appears in the list, and Antigravity opens your browser to complete the SeekOut sign-in.
5
Confirm the connection
A green dot and a Sign out button next to seekout mean you’re connected. Expand tools enabled to see the available SeekOut tools, and leave the toggle on.

Start using SeekOut MCP
Use SeekOut to find senior backend engineers in Seattle with distributed systems experience.
Each user can access only the data and actions allowed by their SeekOut role.
1
Open the MCP configuration file
Antigravity reads MCP servers from a global file, and optionally from a workspace file that applies to one project:
Global (macOS and Linux): ~/.gemini/config/mcp_config.jsonGlobal (Windows): %USERPROFILE%\.gemini\config\mcp_config.jsonWorkspace: .agents/mcp_config.json
2
Add the SeekOut server
Add the seekout entry inside mcpServers, keeping any servers you already have:
In the app, open Settings → Customizations → Installed MCP Servers and click the refresh icon. In the CLI, type /mcp and reload the servers from the MCP manager.
4
Sign in to SeekOut
Complete the SeekOut sign-in when Antigravity opens your browser. Once you’re connected, seekout shows a green dot and a Sign out button.
5
Start using SeekOut MCP
Use SeekOut to compare the data engineering talent pools in Austin and Denver.
Expanding tools enabled lists everything SeekOut exposes — search, market analysis, profile lookups, workspace actions, and more.
The SeekOut tools available to Antigravity agents
Antigravity uses the key serverUrl for remote MCP servers. Configuration copied from other clients often uses url, which Antigravity does not recognize.
Antigravity registers itself with SeekOut automatically using OAuth 2.1 with Dynamic Client Registration, so there is no client ID or client secret to enter. Each person signs in with their own SeekOut account, and every request runs with that user’s SeekOut permissions and entitlements — the same access they have in the SeekOut web app.Your organization’s own policies for AI tools and connected data sources still apply. See Security overview and Authentication for details, or the Security and legal FAQ for security review material.
Confirm the entry uses serverUrl rather than url, and that the JSON is valid. Then click the refresh icon in Settings → Customizations → Installed MCP Servers, and restart Antigravity if the server still doesn’t connect.
Open Settings → Customizations → Installed MCP Servers and click the refresh icon to retry the connection. If seekout already shows a Sign out button, it is authenticated — sign out and refresh to start a fresh sign-in.
