MCP server is already active.

Error message

MCP server is already active.

What it means

State guard in the approve flow: the targeted MCP server's approval_status is already 'active', so a second approval would be a no-op re-registration. Only pending or previously-rejected servers may be approved; firing on idempotent duplicate approves.
