Compare Bay with its top three alternatives side by side

Stay with Bay if you need a fleet-wide inventory of AI agents, MCP servers, extensions and credentials on devices, you need to evaluate or stop individual tool calls before they run, you want context-aware rules and answers beyond allow and block, you want a light rollout with published deployment detail, ideally through existing EDR or MDM and you need an audit record that separates agent actions from human actions. Shortlist Bay if your developers and knowledge workers run coding agents and MCP servers on their own machines, you want a decision on each risky action rather than a report after the fact, and you prefer to deploy through the EDR or MDM you already operate. It suits teams that are ready to adopt AI widely and want the control layer in place first.
