shyn is a Model Context Protocol (MCP) server: Local-first ambient memory for your Mac — pages, meetings, notes, encrypted on-device. Because it speaks the Model Context Protocol, AI assistants can use shyn as a set of callable tools instead of you copy-pasting between apps.
No credentials are required — it works out of the box. The current release is v0.4.30-alpha, with source at shyn-labs/shyn on GitHub.
On mcp.site, shyn sits in the Memory category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below. If you maintain shyn for shyn.day, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
