Show HN: Ctxvitals – a vitals check for your AI agent stack (npx ctxvitals) (github.com)

A new tool called **ctxvitals** has been launched, enabling users to analyze the token cost of their AI agent stacks with a single command. The utility evaluates various components of the agent environment—such as MCP servers, skills, and commands—highlighting actual costs before any input is processed. This transparency is especially valuable for developers managing large setups, where token consumption can soar into the tens of thousands per interaction based on various configurations. The significance of ctxvitals lies in its ability to offer a comprehensive report card on resource usage and security vulnerabilities, addressing the need for greater accountability in the AI/ML ecosystem. By revealing costs associated with always-loaded tokens and potential security flaws like hardcoded API keys, this tool helps developers optimize their configurations and manage expenses more effectively. Moreover, with features like a public leaderboard for popular MCP servers and CI integration, ctxvitals fills a critical gap in resource management, fostering a more sustainable and secure approach to deploying AI agents.
