vest_estimate_cashback
ActiveTool of io.github.VestOSAI/vest-mcp
declared in 2.0.0
Estimate how much cashback a user would earn on their AI tool subscriptions via Vest. Pass subscriptions with monthly costs; Vest accounts for loyalty tier (5–20% depending on total spend). Use when the user asks 'how much could I save?', 'what's my cashback estimate?', or is evaluating whether to join Vest. No API key required. Do NOT use this to recommend tools — use vest_build_stack. Do NOT use this to check what the user already has on Vest — use vest_get_account.
