Attestor MCP
Attestor is a self-hosted memory service for multi-agent production meshes that provides auditable, deterministic retrieval with role-based access control, provenance tracking, and temporal supersession. It operates as a Python library, REST sidecar, or MCP server, ensuring governance and security without LLMs in the critical path.
