Quality: 33/100 (Emerging) | Auth: No auth required
Desktop Touch MCP
OS Automation · Local stdio
Quality: 60/100 (Good) | Auth: No auth required
Verdict Summary: Choose How Persistence Works if you need specialized OS Automation tools running via a hosted cloud SSE transport. Choose Desktop Touch 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 How Persistence Works when:
You need dedicated capabilities in the OS Automation domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Visual Desktop Bridge - Give any AI full control over Windows to automate apps and inputs.
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.

Desktop Touch MCP Tools (23)
desktop_discover
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.
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).
How Persistence Works is categorized under OS Automation and uses a remote streaming HTTP/SSE transport. In contrast, Desktop Touch MCP belongs to OS Automation using local stdio subprocess. Select How Persistence Works when you need capabilities focused on os automation and Desktop Touch MCP when you require tools for os automation.
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).
workspace_snapshot
Instant session orientation: all window thumbnails + UI summaries in one call.
server_status
Diagnostic check for native engine health and feature activation.
