Cursor

Cursor uses the same local command and the same two tools as every other editor. Kaleidoscope makes the change to Cursor’s JSON reversible, and adds a small project rule only if you ask for one.

Connect it

kaleidoscope connect cursor --profile default --project "$PWD" --dry-run
kaleidoscope connect cursor --profile default --project "$PWD"
kaleidoscope instructions install cursor --project "$PWD"

What it writes

The MCP server entry goes into Cursor’s JSON configuration. Entries you added yourself are left untouched. A tampered marker, a name that conflicts, a malformed file, a symlink, or a file being edited at the same time is refused and handed back to you rather than overwritten.

The one thing that is different here

The project rule is a second, separate file from the MCP configuration. connect cursor writes the server entry; instructions install cursor writes the rule. They are installed and removed independently, so removing one leaves the other in place. If Cursor can see the tools but ignores them, it is usually the rule that is missing — see give your agent the skill.

Disconnect

kaleidoscope disconnect cursor --project "$PWD"
kaleidoscope instructions remove cursor --project "$PWD"

Each removes only what Kaleidoscope wrote. Run both if you installed both.
