From Tools to Traces: Why MCP is the Key to Agentic Data Lineage

This piece is in progress — check back soon.

We're publishing the full analysis shortly: why traditional observability stops

at the tool-call boundary once an agent is the one moving your data, and how

the Model Context Protocol supplies the structural audit trail that brings

agentic behaviour into the realm of formal data governance — moving from

*watching if an agent works* to *governing the data it touches*.

Deep dive: for the technical implementation — MCP as the telemetry source,

combined with OpenTelemetry and OpenLineage — see [Mapping the MCP Protocol:
