X_MCP_CONFIRMATION_QUORUM_PENDING
Means
an MCP confirmation needs more approvers before the call runs
Typical cause
mcpConfirmations({ approvers }) resolved a quorum above one for this call and fewer distinct approvers have approved; the asking actor never counts, and one approver counts once
Fix
confirmations({ id, decision: 'view' }) — as another approver the quorum names, then approve with exactly the arguments it returns
