Action Gateway connects applications and AI agents to tools through a managed MCP endpoint or SDK, with the accounts and permissions you choose. See What You Can Build for standalone agent examples.
Endpoints
Action Gateway endpoints provide MCP access to versioned tools and permissions for an actor.
Actors
An Action Gateway actor ID associates a user’s or workload’s connected accounts with its endpoints.
Connections
Action Gateway connections let tools use a specific account at a service such as GitHub, without exposing its credentials to the agent.
Toolbelts
Action Gateway Toolbelts group tools into versioned collections for endpoint selection, group permissions, and preloading.
Tool Policies
Action Gateway tool policies allow, require approval for, or deny calls within an endpoint version’s selected catalog.
Preloading Tools
Action Gateway preloading exposes known tools directly to the model while tool search discovers other relevant tools as needed.
Tool Search
Action Gateway tool search discovers relevant catalog tools and their schemas without loading the entire catalog into an agent’s context.
Invoke Tool
Action Gateway invokes named catalog tools with validated arguments and returns an outcome for each call.
Code Execution Tool
Action Gateway runs an agent’s Python code in an ephemeral sandbox, with optional programmatic tool calling for advanced workflows.
Reliable Execution
Action Gateway uses bounded, tool-specific retries and provider idempotency where supported, without guaranteeing that arbitrary repeated calls are safe.
