Augment Code has built-in memories and a Context Engine. Here is how to extend them with cross-tool persistent memory via MCP so your context follows you across every coding tool.
Supermaven has a massive 1M token context window but no cross-session memory. Here is how to add persistent memory via MCP so Supermaven remembers your project decisions and conventions.
A technical deep-dive into MCP memory servers: what they are, how they differ from other MCP servers, and how MemNexus implements the full extraction-graph-retrieval pipeline.
Context windows give coding agents short-term recall. MCP gives them a persistent memory layer — decisions, patterns, and architecture knowledge that survive every session restart.
Connect MemNexus via MCP server or CLI to extend Cursor Memories across projects, agents, and tools — one command, no manual rule edits.
