Is Mercury MCP worth the price?
Mercury's pricing is generous for basic banking at $0/mo, but the $29.90/mo Plus and $299/mo Pro tiers add modest features for steep jumps, especially with per-transaction and per-user fees.
Compared to other neobanks, the free tier is competitive, but Plus and Pro feel expensive for what they offer beyond standard banking. Best for startups needing simple banking at no cost, but growing teams should watch for hidden costs.
Hidden Costs & Gotchas
ACH debit $1/transaction on Plus tier
$5 per additional active user beyond limits
Treasury requires $250K balance to unlock

How Mercury MCP Compares to Competitors
Mercury's free tier undercuts most competitors like Brex or Rho, which often require higher balances or fees for basic features. However, Mercury Plus and Pro are pricier than similar tiers from neobanks like Relay or Lili, especially with per-user and per-transaction add-ons. The value is strongest for startups that can stay on the free plan, but less so for teams needing advanced invoicing or reimbursements.
