Corresync MCP
A local-first Model Context Protocol server and CLI that aggregates mail, calendar, and task data from multiple providers like Outlook, Gmail, and Todoist. It keeps account identities isolated, ensures agents never hold credentials, and enforces a preview-before-commit safety model for writes.
