Give Every Agent Exactly The Tools It Needs

Gateway is presented as a centralized access-control layer for AI agents that addresses overly broad shared credentials, unprotected internal APIs, and static permissions by separating connector authentication from per-agent tool authorization. Administrators can connect MCP servers through OAuth or internal APIs through OpenAPI specifications, while Gateway securely stores upstream credentials and issues each agent a single constrained key with configurable expiration, rate limits, and spending caps. Agents receive only explicitly granted tools, can discover available authorized tools without loading an entire connector catalog into context, and may request additional access for administrator approval when their tasks change. All allowed and denied calls are recorded with agent-level details and reasons, while request and response bodies follow configurable retention policies. Administrators can modify permissions, revoke individual agents immediately without rotating upstream credentials, apply reusable grant policies, and migrate existing agent integrations gradually; the system is built and used by mem0 for its own production agents.
