MCP gateway
A proxy between agents and MCP servers that tool listings and tool calls pass through, so one place can authenticate, allow or refuse servers and tools, inspect arguments and results, and log. It sees only the MCP traffic routed through it: a server an agent connects to directly, and actions that are not MCP calls, such as shell commands and file reads, are outside it.
How MoorAI handles it: moorai-mcp-gateway sits in front of remote MCP servers and evaluates every tools/call; a stdio proxy does the same for local servers.

Where the attacks above actually land. The vocabulary here is worth precision, because the difference between "the model decided" and "the tool ran" is the difference between a risk and an incident.
