Five passes between a source and an answer that cites itself.

Every source runs through five passes. What enters as a raw meeting, doc, or video leaves as a queryable graph — typed, linked, and cited back to the moment it came from.

— For agents · §04FIG. 04 / MCP · READ

Your agents read the same graph you do. Cite, trace, and write back through one endpoint.

Any MCP-compatible client speaks to the graph through one endpoint. Agents can read cited knowledge, apply skills you’ve authored, and write back new decisions.
