## Summary

A paper on arXiv introduces an architectural mediation approach using the Model Context Protocol (MCP) to connect large language model agents with data space services. The authors implement the Eunomia Agent as a prototype that translates data space capabilities into structured, schema-driven tools. This allows AI agents to discover and invoke data services while preserving governance constraints. The prototype demonstrates end-to-end interaction across catalog discovery, metadata retrieval, and data service invocation without modifying existing data space components. The authors state the approach enables interoperable, standards-aligned integration of AI agents into governed data-sharing environments.

## Key points

- Proposes MCP-based mediation layer for LLM agents and data spaces
- Eunomia Agent prototype validates catalog discovery and data invocation
- Approach preserves governance without modifying data space components

## Why it matters

Shows a path to integrate AI agents into regulated data ecosystems while keeping compliance and architectural separation.
