How is Rook different from other MCP servers?
Rook is purpose-built for the Rook notes app and uses its native binary with app-group entitlement for seamless data transfer. Standalone builds cannot function due to entitlement checks.

Rook is an MCP server that saves text from AI chats into Rook, the notes app for code. It integrates with the Rook app via a signed binary using stdio JSON-RPC 2.0. Targeted at developers who want to capture AI-generated notes into Rook.
Install Rook from userook.app, then add to your MCP client config with the command path /Applications/Rook.app/Contents/Helpers/rook-mcp.app/Contents/MacOS/rook-mcp. The server provides one tool: append_to_inbox, which accepts title and content parameters.
append_to_inbox with title and content.entitlement_unavailable.Rook is purpose-built for the Rook notes app and uses its native binary with app-group entitlement for seamless data transfer. Standalone builds cannot function due to entitlement checks.
Requires Rook to be installed from userook.app. The server binary is bundled inside the Rook app and must be run from that location.
Data is sent to the Rook app via the app-group entitlement, where it is saved as notes within Rook.
The README does not mention limits beyond the requirement for the Rook app to be installed and the standalone build restriction.
Rook uses stdio JSON-RPC 2.0 transport. No authentication is described; it relies on local file system access.
