memex
Gives Cursor, Claude Desktop, and other MCP clients a SQLite-backed memory that survives across chats. You tell it once to remember your coding preferences, stack decisions, or project conventions, then open a new conversation later and the agent recalls them without re-prompting. Ten tools cover the basics: remember to store a fact, retrieve_context to pull relevant memories sized for your token budget, recall for keyword search, update_memory to revise entries with history preserved. Everything stays in a local database file under ~/.memex. Useful when you're tired of re-explaining your testing style or branch naming rules every session. Optional hybrid search mode helps with paraphrased queries. Built in Go, runs via stdio, requires no cloud account or API keys.
