Open Data Governance Standard (ODGS) — MCP Server

Deterministic governance enforcement at the AI agent boundary.

For engineers: See Quick Start below.
For compliance and risk officers: The ODGS engine generates cryptographic audit trails (S-Certs).

[!IMPORTANT] ODGS MCP Server v0.2.0 — Maturity Diagnostics + Certified Pack Access governance_score now delegates to the odgs-maturity 8-pillar DAMA DMBOK engine. Regulatory compilation, drift detection, and catalog synchronisation require a Certified Pack licence. The community tier — validation, scoring, conformance checking — remains open with no registration.

---

What's New in v0.2.0

Change	Detail
governance_score	Delegates to odgs-maturity (8-pillar DAMA DMBOK) when installed; falls back to built-in heuristic. Returns 0–100 score with per-pillar gap analysis.
AuthGate	Community / Professional / Enterprise access via API key validation. 24h disk cache; workspace.yaml fallback for air-gapped deployments.
Licensed tools	compile_regulation, check_drift, detect_conflicts, narrate_audit, discover_bindings (Professional); sync_catalog, harvest_sovereign_rules (Enterprise).

The European Data Governance Maturity Benchmark 2026 recorded an average maturity of 37.6% across 99 enterprises — a 62.4% gap against current regulatory expectation. governance_score applies the same assessment methodology to your project.

What This Is

The ODGS MCP Server connects any MCP-compatible AI agent to the ODGS Sovereign Validation Engine. The engine evaluates data operations against governance rules at runtime and produces S-Certs (Sovereign Certificates) — cryptographically signed, machine-verifiable records that a governance rule was applied.

This is the bridge between probabilistic AI inference and deterministic governance enforcement.

EU AI Act & High-Risk AI Systems

Organisations operating High-Risk AI Systems under EU AI Act Articles 10 and 12 require demonstrable, auditable data governance at the pipeline level. S-Certs provide that audit trail in a format suitable for regulatory submission.

Certified Sovereign Packs and the S-Cert Registry are available through Metric Provenance certified implementation partners. For architectural assessment: metricprovenance.com/brief.

Capabilities

• Runtime validation: Data payloads are evaluated against sovereign governance rules at call time; each evaluation produces a signed S-Cert.
• Governance maturity scoring: 8-pillar DAMA DMBOK assessment (0–100) with per-pillar gap analysis, aligned to the European Governance Maturity Benchmark methodology.
• Regulatory compilation (licensed): Converts legislative text — EU AI Act, DORA, GDPR — into validated ODGS rule JSON.
• Semantic drift detection (licensed): Identifies definitional drift between governance artefacts across versions.
• Enterprise catalog integration (licensed): Harvests and mints sovereign rules from Databricks, Snowflake, and Collibra via the Flint Bridge.

Quick Start

# Core validation capabilities (free, no account needed)
pip install odgs-mcp-server

# With maturity scoring
pip install odgs-mcp-server odgs-maturity

# Complete installation with LLM bridge capabilities
pip install "odgs-mcp-server[llm]"

Client Configuration

The server operates over standard stdio transport, making it instantly compatible with any MCP client.

Architecture

The ODGS MCP Server is designed for zero-trust, local-first execution. All data validation happens strictly on your machine. No sensitive data leaves your perimeter.
