Which MCP Server Should You Choose?
Choose Desktop Touch MCP when:
You need dedicated capabilities in the OS Automation domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Windows desktop automation for LLM agents with entity-based actions instead of coordinate-only clicking. Uses UIA, CDP, screenshots, keyboard/mouse/clipboard, and terminal control, plus entity leases, verified delivery, causal context, and interaction memory to reduce silent UI automation failures.
MCP server for macOS Calendar.app — calendar and event management via AppleScript
Observe the desktop. Returns interactive entities with leases (UIA, CDP, Terminal, Visual SoM).
desktop_act
Perform actions (click, type, drag, select) on entities via lease validation. Returns semantic diffs — plus an optional `roiCapture` (changed-region PNG + next-target preview) on visual-only targets.
desktop_state
Lightweight check of focus, active window, cursor, and Auto-Perception attention signal.
screenshot
Multi-mode capture: `detail='text'` (UIA/OCR), `diffMode` (P-frame), `dotByDot` (1:1), and `background`. Returns a cheap `screenshot://by-ref/{id}` link to the saved image instead of inlining pixels every time.
screenshot_query
Inspect and prune the on-disk screenshot cache behind the by-ref links: `screenshot_query` lists saved captures without re-reading pixels; `screenshot_gc` reclaims space by retention policy (dry-run by default).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Desktop Touch MCP is categorized under OS Automation and uses a local stdio subprocess. In contrast, Calendarmcp belongs to OS Automation using local stdio subprocess. Select Desktop Touch MCP when you need capabilities focused on os automation and Calendarmcp when you require tools for os automation.
