About samvallad33/vestige
Vestige is a local-first long-term memory system for AI agents, implemented as an MCP server. It stores memories in a local SQLite file, enabling agents to remember decisions, catch contradictions, and trace failures back to their root causes. Built in Rust with a single 25MB binary, it requires no cloud, no API keys, and works fully offline after a one-time model download. Vestige applies cognitive science principles to memory management: merging redundant memories, superseding contradicted ones, preserving frequently used knowledge, and allowing unused memories to decay.

FAQ
How does Vestige work?
Vestige runs as a local MCP server that stores memories in a SQLite database. It uses cognitive science principles to manage memory, merging redundant information, superseding contradicted facts, and fading unused memories. It can trace failures backward to the earlier memory that caused them, even if they share no common vocabulary.
Is Vestige free?
Yes, Vestige is open source and free to use. It requires no API keys or subscriptions.
Which AI agents are compatible?
Any MCP-capable agent, including Claude Code, Claude Desktop, Codex, Cursor, Cline, Continue, Zed, and Goose.
Do I need an internet connection?
After a one-time model download, Vestige works fully offline with no internet connection required.
