Delx Memory
A shared SQLite key/value store that any MCP client can read and write, so your context survives when you switch from Claude Desktop to Cursor or restart a session. It gives you eight tools: four read-only (stats, list, get, and full-text search with bm25 ranking), four mutating (set, forget, tag-based bulk delete, and JSON export). Mutations require explicit_user_intent flags so agents can't silently rewrite your memory. It blocks credential-shaped strings (JWTs, Bearer tokens, AWS keys, API secrets) and stores everything at ~/.delx-memory/db.sqlite with 0600 permissions. Useful when you need preferences, project context, or session state to follow you across tools and survive restarts without manual copying.

Readme
delx-memory
Local-first persistent memory MCP server. One shared SQLite store any MCP-speaking agent (Claude Desktop, Cursor, Hermes, OpenClaw, Codex) can read and write — so context survives across sessions AND across tools.
