Building Cursor Memory via MCP & Supermemory (May 2026)

Cursor does not retain conversational context between sessions by default, so the proposed approach combines a version-controlled, file-based memory bank with an external Model Context Protocol (MCP) memory server to preserve project knowledge over time. A memory-bank directory can contain structured Markdown files for project goals, current work, progress, and technical decisions, while Cursor Rules remain separate as relatively static instructions for coding standards and behavior. In Cursor’s Plan and Act workflow, relevant memories can be retrieved before reasoning and new information saved after work is completed, allowing context to persist within and across repositories. The text emphasizes that retrieval should be narrowly scoped to control token costs and latency, and that stored memory must be reviewed regularly because outdated summaries can mislead future work. It presents Supermemory as an optional external layer offering project-scoped Profiles, Connectors for sources such as GitHub, Notion, and Slack, and semantic SuperRAG retrieval, while advising teams to protect sensitive memory files through version-control exclusions and environment-based secret management.
