Lumen MCP Context Inspector
Drop-in MCP server and execution-metrics recorder for Bedrock-based agents and Claude Code. It records per-session cost, token and tool metrics, then renders a Context Window Explorer over a real MCP handshake so teams can inspect visible context and invisible overhead. Public GitHub repository created August 18, 2026.
