Signal Desk by LarryBuildsAI

larrylemonbot/signal-desk-mcp-server

This sits between your AI agent and expensive tool calls to add a validation checkpoint. The idea is straightforward: before your agent burns through API credits or triggers costly operations, this server gives you a lightweight decision gate to confirm, modify, or block the action. Reach for it when you're running agents that interact with paid services, production databases, or any tool where a mistake gets expensive fast. The source is minimal on implementation specifics, but the value proposition is clear: it's a circuit breaker for agent spending. Think of it as a confirmation dialog for your autonomous workflows, especially useful during development or when testing new agent behaviors against real systems.
