Action Gateway Quickstartpublic
Last verified 21 Sep 2026
Action Gateway gives applications and AI agents governed access to tens of thousands of tools through a managed MCP endpoint or SDK. See What You Can Build for example use cases of Action Gateway with Harness Runtime.
Connect Action Gateway to your coding agent, then ask it to find and run tools. You need a DigitalOcean account and either Claude Code or Codex installed.
1. Create a Session
- Open Action Gateway Sessions in the Control Panel and click Create session.
- Enter a Session Name, such as
coding-agent, and keep the default settings. The default Ask permission policy requires your approval before tools run. - Create the session and copy its MCP URL.
2. Connect Your Coding Agent
Choose your agent below. Run the commands in a terminal from your project directory, replacing <action-gateway-session-mcp-url> with the URL you copied. When prompted, sign in with the DigitalOcean account you used to create the session.
Add Action Gateway and start browser sign-in:
codex mcp add action-gateway --url "<action-gateway-session-mcp-url>"
codex mcp login action-gatewayAfter signing in, run codex to start a new coding-agent session.
Add Action Gateway:
claude mcp add --transport http action-gateway "<action-gateway-session-mcp-url>"Run claude in the same project directory. In Claude Code, run /mcp, select action-gateway, and follow the browser sign-in prompts.
3. Try a Tool
Send this prompt to your coding agent:
Use Action Gateway to list available DigitalOcean Droplet sizes. Do not create, update, or delete any resources.Review and approve the read-only call when prompted. Your agent finds the tool, runs it, and returns a list of Droplet sizes.
This example does not require a prepaid balance, but tool invocation charges apply.
You can reuse this session for future tasks. To use tools from other services, authorize their providers. For SDK setup, see Connect Action Gateway.
