Bastion

Bastion is a macOS menu-bar application that manages MCP servers by running a single supervised instance per profile instead of spawning multiple server processes per client. It centralizes credentials in the macOS Keychain, records all tool calls for auditing, and offers streamlined control over multiple servers and profiles to reduce resource usage and improve security. It provides a unified gateway URL for clients, supports detailed activity logs, and is sold as a $14.99 paid app with a 30-minute trial.
