Every time you start a new Claude Code session, your AI has zero context about what you were working on. Same with Cursor, Cline, Windsurf. You spend the first few minutes re-explaining the codebase, the decisions you made, where you left off. It's annoying.
I got tired of it and built something to fix it.
What it does
sessionmem is a local-first MCP server that watches your coding sessions and auto-injects a compact summary at the start of each new one. Your AI instantly knows what you were working on, what decisions were made, and what's next.
The compression is aggressive. Instead of feeding the full conversation history into context (expensive, often impossible due to token limits), sessionmem distills sessions down to just the key facts. In testing we're seeing 85.6% token reduction compared to keeping full history.
