Download Sift
Install Sift to protect all your MCP servers through a single security layer with policy enforcement and monitoring.
Release Notes
Initial release — MCP proxy, policy templates, audit logging, and Claude Code hook support.
Important: macOS may show a “damaged” warning
Since Sift is not yet notarized with Apple, macOS Gatekeeper may block the app after downloading. To fix this, install Sift normally (drag to Applications), then open Terminal and run:
xattr -cr /Applications/Sift.app
This recursively clears the quarantine flags macOS adds to downloaded files. After running this command, Sift will open normally. We're working on Apple notarization to eliminate this step.
