Why it matters
Tool connections can let agents take actions or access data. A gateway gives teams a place to apply identity, policy, and human review to supported traffic.
How it works
An MCP gateway sits in the request path between an agent and connected tools. Available controls depend on the gateway, policy, and server configuration.
How Halo approaches it
Halo provides a separate MCP and tool gateway for agent traffic, with configured identity, policy checks, approvals, budgets, and reviewable evidence.
