Show HN: I built flightdeck – Observability and control plane for AI agents

flightdeck is a self-hosted, Apache 2.0 observability and control plane that streams every LLM call, MCP event, and tool call from AI agents to a dashboard with a per-agent timeline and live fleet-wide feed. It offers token budgets with warn/swap/block thresholds, a kill switch and remote directives, per-flavor MCP allow/block rules, and sub-agent trees, and agents attach via a Claude Code plugin or the flightdeck-sensor Python package using init() + patch(). It is not a proxy: the sensor wraps SDK clients inside the agent's process and calls go straight to the provider, with prompt capture off by default in the sensor.
