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 Tools
Create Action Gateway connections for provider accounts and use actors to select which connections a session uses.
Add a remote MCP server to Action Gateway with no authentication, an API key, or an OAuth connection.
Use Action Gateway Tool Playground to find and run tools in a model conversation, then inspect calls and results.
Manage Tool Access
Group Action Gateway tools into a versioned Toolbelt, then select that version in a session or environment spec.
Create an Action Gateway session to get an MCP endpoint URL with the tools and permissions your client needs.
Require approval for Action Gateway tool calls and handle the decision through MCP elicitation or a separate approval request.
Create an Action Gateway output view that keeps selected result fields and bind it to a new session.
Configure production agents with selected tools, explicit permissions, preloading, direct Python calls, and focused tool outputs.
