Three finance platforms in 72 hours moved from recording money to executing finance work, and all three put MCP underneath.

Bujeti launched BRAIN on September 18 with four named agents on a shared ledger, including Chaser, which negotiates payment plans over email, SMS and WhatsApp and claims a 3.2x recovery rate on difficult accounts in testing, plus a planned MCP server so outside agents can query finance data under customer permissions. Findity announced agents on September 17 that capture receipts, match card transactions, check policy and post to accounting, shipped embedded via API or white label. Mercury launched Books on September 16, a full double-entry engine inside the bank account, free through 2026 then $35/month, with an accounting API and MCP layer planned. Mercury Beta partner Ridgewood, serving 200+ monthly clients, says it halved manual bookkeeping time. The system of record is repositioning as something agents call.
