Mapping the MCP Protocol: Implementing D/I O11y for Agentic Data Flows

This piece is in progress — check back soon.

We're publishing the full technical walkthrough shortly: implementing Data &

Information Observability (D/I O11y) at the protocol level, using MCP tool-call

interception as the telemetry source and joining OpenTelemetry traces with

OpenLineage events into a single, verifiable, end-to-end semantic lineage

record.

Strategic framework: this build implements the model set out in [From Tools

to Traces: Why MCP is the Key to Agentic Data

Lineage](https://www.bearingnode.com/post/agentic-lineage-mcp-dio11y) — read

that first for the governance case this makes technically real.
