delx-memory

Local-first persistent memory MCP server that provides a shared SQLite-backed key/value store for multiple MCP-speaking AI agents (Claude Desktop, Cursor, Hermes, OpenClaw, Codex). Version 0.2.2 (alpha), open source (MIT), Node.js >=20 required. Unlike ephemeral per-client memory solutions, delx-memory enables cross-session and cross-tool context persistence via a single SQLite file at ~/.delx-memory/db.sqlite. Features 8 MCP tools (4 read-only, 4 mutation requiring explicit user intent), TTL support, tags, prefix filters, FTS5 full-text search, secret-blocking for credential-shaped keys/values, and zero telemetry. The server is designed as a lightweight MCP tool, not a generalized database.
