I Built a Secure Planning Agent with MCP and Keycard (www.keycard.ai)

A developer has created "Plan My Today," a personalized AI planning agent named Todaygent that utilizes MCP (Multi-Channel Platform) to unify various productivity tools like Google Calendar, Slack, and GitHub into a single dashboard. This AI agent helps users prioritize tasks and prepares for meetings by analyzing real-time data from multiple sources without disrupting the user's existing workflow. Unlike traditional productivity tools, Todaygent maintains read-only access to users' data and does not autonomously mark tasks as complete, allowing individuals to retain control over their task management while benefiting from AI-enhanced organization. This innovative approach is significant for the AI/ML community as it showcases advanced reasoning capabilities in a secure context. The architectural design leverages Keycard for secure authorization, employing ephemeral tokens for third-party access to protect user credentials from long-term vulnerabilities. This solution not only provides a seamless user experience by running API token exchanges in parallel, streamlining the planning process, but also emphasizes accountability through comprehensive audit logs. This dual focus on user control and security establishes a promising model for future AI applications aimed at enhancing productivity while safeguarding personal data.
