MCP-Memory: OKF-Backed Agent Memory Server
MCP-Memory is a Model Context Protocol (MCP) server that equips AI agents (such as Claude Desktop, Cursor, Antigravity, Windsurf, or Codex) with persistent, long-term memory capabilities.
Memory records are formatted using the Open Knowledge Format (OKF v0.2) standard and indexed with a local SQLite instance (supporting FTS5 full-text search) for fast key-value lookups, tag filtering, and content search.

Dual-Layer Architecture: Human-Browseable OKF Directory : Automatically dumps and syncs every memory to disk as a raw .md file inside the memory/ bundle directory with hierarchical index.md progressive disclosure files (root index.md versioned with okf_version: "0.2" ) and log.md update history tracking. High-Performance SQLite Indexing : SQLite FTS5 (Full-Text Search) and automatic triggers for sub-20ms key lookups and instant keyword searches.
Namespace Isolation: Supports contextual separation (e.g. user/preferences , project/architecture , default ).
Supports contextual separation (e.g. , , ). Zero Boilerplate Setup: Quick setup wizard ( python3 setup.py ) auto-configures installed MCP tools (Antigravity, Claude, Cursor, Windsurf, Codex).
