GrayMatter

Self-hosted persistent memory for AI agents, cutting token usage 90%

PlatformWebfreeglobal

GrayMatter gives AI agents persistent memory in three lines of code, cutting token usage by 90% — one binary, no Docker, no databases, no config files, no cloud accounts. A general-purpose MCP server with zero vendor lock-in, working with Claude Code, Cursor, Codex, OpenCode, Antigravity, and any MCP-compatible client (also usable as a plain Go library).
