Vayl MCP

Vayl is an open-source reconciling memory layer for AI agents that supersedes old facts with new values while maintaining a queryable, auditable history. It runs locally over stdio with SQLite or as an authenticated team server, supporting high-stakes changes requiring human approval and compliance features like GDPR erasure.
