Model Context Protocol ecosystem expands with note-taking, health diagnostics, and manufacturing servers

Multiple developers are shipping Model Context Protocol servers for Claude Code and related tools, according to GitHub and blog sources. Jot, a Mac note-taking app, released an MCP server that lets Claude Code list, search, and read local Markdown notes without requiring API keys or cloud sync. Mac Health MCP, a read-only server, enables Claude to diagnose system performance issues by checking uptime, memory, disk usage, busy processes, and battery status on macOS.
