At a Glance & Executive Verdict
Desktop Touch MCP
OS Automation · Local stdio
Quality: 60/100 (Good) | Auth: No auth required
Mac Control MCP
OS Automation · Local stdio
Quality: 55/100 (Good) | Auth: No auth required
Verdict Summary: Choose Desktop Touch MCP if you need specialized OS Automation tools running via a local process. Choose Mac Control MCP if your workspace requires OS Automation integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
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.
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, Mac Control MCP belongs to OS Automation using local stdio subprocess. Select Desktop Touch MCP when you need capabilities focused on os automation and Mac Control MCP when you require tools for os automation.
Precision coordinate-based interaction with homing and force-focus protection.
scroll
Multi-strategy: `raw` (notches), `to_element`, `smart` (virtual lists), and `capture` (stitch).
click_element
Legacy UIA-based click by name/ID (fallback when entities are unavailable).
browser_open
Idempotent debug-mode launch and reliable navigation.

Mac Control MCP Tools (10)
capture_screen
main display (or a rectangular region within it) to a PNG file, returns the file path + width/height. Simple, synchronous, no size limits applied.
capture_screen_v2
main display only, but stores the PNG as a content-addressed artifact under `~/.mac-control-mcp/artifacts/<sha256>.png` and returns `{content_ref, bytes, sha256}`. Defaults to `inline=false` and downscales to `max_dimension`/`max_bytes` (4000px / 4MB by default) specifically to avoid blowing up an…
capture_window
screenshots one specific window by PID (optionally filtered by `title_contains`), not the whole display.
capture_display
screenshots one specific physical display by its index from `list_displays`, for multi-monitor setups.
list_elements
lists actionable elements for a PID (a flat, practical "what can I click" view).
find_element
returns the *first* element matching a role/title filter for a PID.
find_elements
same matching as `find_element`, but returns *all* matches, not just the first.
query_elements
regex search over role/title/value (falls back to case-insensitive substring on invalid regex); use when a plain role/title filter isn't precise enough.
get_ui_tree
walks the *full* accessibility tree of a process, including containers, and assigns stable element IDs for follow-up calls. Heavier than `list_elements`/`find_element(s)`, but the only one that gives you structure/hierarchy.
ax_tree_augmented
like `get_ui_tree`, but does one OCR pass and geometrically joins OCR-derived labels onto AX nodes that have no native label. Use it specifically for Electron/Chromium/Canvas apps where the native AX tree is sparse and unlabeled; it's the expensive option (an OCR pass), so reach for `get_ui_tree` f…
