Agience/agience-core

Artifacts with versioned content and stable IDs serve as the primary interface between humans and agents, replacing documents and chat history as the unit of shared state. The system implements provenance, access control, and human approval as structural primitives—commit gating, scoped API keys tied to identity, and immutable transformation records—rather than policy overlays. Built as an MCP-native platform with composable FastMCP server modules for ingestion, retrieval, reasoning, and governance, it integrates third-party MCP servers while maintaining a graph database backend for typed, auditable state.
