ui-control from dcc-mcp/dcc-mcp-core is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Infrastructure skill for application UI observation, scoped action, waits, and CUA trajectory recording when a typed DCC tool cannot expose the needed interface. Use this skill when the user asks for CUA, UI Control, dcc-cua, or application UI automation in a DCC. Prefer typed DCC tools first and CDP for browsers; use the standalone dcc-cua backend for native applications.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DCC UI Control The Agent Host owns user authorization. Core never enables the standalone Host's legacy native confirmation popup, including when menu invocation is allowed. Missing authorization remains a typed refusal; do not auto-approve or retry it through another input route. For bounded task authorization, use the project-owned DCC-CUA task bridge and its exact target/scope checks. Use application UI automation only when a typed DCC skill, host API, or adapter script reports `unsupported` or `capability_missing`. Policy denial, user interruption, authentication, and desktop unavailability are stop conditions. ## Backend order 1. Use a typed DCC-MCP tool whenever one exists. 2. For Chrome, Edge, launchers, and embedded webviews with DevTools access, set `DCC_MCP_UI_CONTROL_BACKEND=chrome` (or `edge`) and use CDP. 3. For native application UI, set `DCC_MCP_UI_CONTROL_BACKEND=cua` and use the standalone `dcc-cua` CLI/Host. 4. `mock` is an explicit deterministic test backend only; production defaults to `dcc-cua` and never silently falls back to mock automation. Core does not package an automation Host in its own release assets. The official …

How to install
mdr add dcc-mcp/dcc-mcp-core/ui-control@sha256:9c535dcc5e1d902aThe line at the top of this page pins the label git:20261023.0460786, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
