DataHub + OKF Governed Query
A security-focused MCP adapter that combines read-only DataHub metadata evidence with a reviewed OKF-derived policy IR before executing a closed, typed query against synthetic PostgreSQL data.
Status
The architecture and implementation slices are specified. Implementation starts with the reproducible TypeScript and Nix foundation.
Core boundary
MCP caller
-> Context MCP
-> pinned DataHub MCP (read-only evidence)
-> private Unix socket
-> Query Executor
-> reviewed Policy IR
-> live PostgreSQL schema and role verification
-> fixed typed SQL
<- validated structured result
- DataHub is evidence, not the authorization authority.
- Runtime authorization is deterministic; an LLM does not decide
ALLOW. - The executor never accepts arbitrary SQL.
- The MVP does not write decisions or query results back to DataHub.
- The demo uses one synthetic dataset and fails closed on ambiguity or drift.
