"Email" matching MCP connectors:

Accounts receivable automation for Xero and QuickBooks Online, inside your AI assistant. Ask Claude, ChatGPT or any MCP agent what your customers said in their email and SMS replies, check a contact or an invoice, and update contact people straight into your ledger. Coming soon: send reminders and statements, record promises and disputes, set up payment plans, work escalations and forecast cash. Secure OAuth sign-in, one organization per connection, Read or Read and Write access.

AI-native operating system for general contractors: estimates, takeoff, bids, pay apps. CooperBuild is built around one idea: the estimate is the company. Approving a proposal clones the estimate into the live project, and takeoff, vendor quotes, pay apps, payroll and the general ledger hang off the same deliverables. Agents can sign up on their own via OAuth dynamic client registration and an email-code bootstrap.
