Pin a workspace and restrict tools

-
Restrict tools with
?tools=, a comma-separated list of tool names or groups:
Troubleshooting
Server shows disconnected or refuses the connection
Server shows disconnected or refuses the connection
Check the workspace slug in the URL. It must match a workspace in your SuprSend account exactly, for example
staging, not the workspace’s display name. A slug that doesn’t exist fails with 403 workspace_forbidden. To see your slugs, remove the slug, reconnect, and ask: “List my SuprSend workspaces.”Tool list
Every tool, grouped by category, with read vs write labels.
