Field notes
Cedulon combines signed receipts, epoch checkpoints, and reconciliation against a payment rail’s extract, making the absence of a receipt an auditable discrepancy rather than an invisible gap. The displayed repository example applies limits of 10 USD per payment, 30 USD cumulatively, and three payments per hour. Its five MCP tools can be launched through npx using @cedulon/mcp-server, according to the homepage.
