signal_show

MCP tool from Open Compute MCP by ellmos-ai

Show the screen-usage signal overlay: glowing border + cursor ring colored per mode (control=red, observe=blue, …); persists in the server process.

How to use it

signal_show is exposed by the Open Compute MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the signal_show tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
