Open the MCP permission portal, choose Permissions, and find the assistant and company you want to change. Select Edit permissions on the active connection.
Clear the capabilities the agent no longer needs, then choose Save reduced access. Related write permissions can also be removed when their required read permission is no longer selected.
This screen reduces existing access. It cannot add a new capability that was not part of the grant. If the assistant needs broader access, start a fresh consent flow and review the expanded request separately.
After saving, ask the assistant to check its current connection permissions before continuing an operation that depended on the removed scope. A prior successful read does not guarantee the same operation remains authorized. Reducing access does not erase records already created through valid workflows, so review any existing work separately. Use Revoke access when the entire connection should stop rather than trying to remove every optional capability individually.
