RailFi MCP
Free, non-custodial MCP server for agent-safe stablecoin payout plans.
RailFi helps teams (and agents) turn invoice/payout rows into a bounded payout-run draft the owner approves once in their own wallet. Tools validate plans and reconcile transfers; they never hold funds or keys and do not execute payments.
