Another major benefit of Anthropic’s Claude Desktop support for remote MCP servers is the ability to combine powerful data access and visualization in notebooks that can be shared via web links.

What’s going on here?
Prompts are being processed through queries executed against a Knowledge Graph (KG)—all thanks to loose coupling. The target KG could reside locally, live on the Web, or be part of the vast Linked Open Data (LOD) cloud.
Architecture? As depicted in the attached image.
BTW -- @Google Gemini can generate pretty accurate diagrams using @drawio XML!
A simple GUI-based screencast demo of the @openlink AI Layer (OPAL), showing what’s now possible via MCP + A2A—namely, composing and orchestrating agentic workflows through loosely coupled software.
How?
An Agent Host routes tasks to Agents via A2A. Agents then invoke MCP-accessible tools (functions, procedures, APIs) described using JSON/YAML and exposed via OpenAPI.
Just another example of the Semantic Web vision in action—modernized for the AI era. 😀

🚀 Virtuoso Open Source 7.2.15 is out!
A high-performance, multi-model DBMS supporting SQL, SPARQL & GraphQL. Also a Web App Server (HTTP, WebDAV, OpenAPI) & MCP-accessible via ODBC, JDBC, pyODBC & DotNet.
🔗 https://community.openlinksw.com/t/virtuoso-open-source-7-2-15-release-notes/5006
💥Boom!
The MCP Server for our OpenLink Software AI Layer (OPAL for short) is now generally available for both cloud-based and on-premise deployment.
This sophisticated and secure implementation of the Model Context Protocol (MCP) supports both client and server roles:

2/ It enables any MCP Client supporting SSE or Streamable HTTP to dynamically discover and invoke:
- SQL, SPARQL & GraphQL queries
- Metadata introspection
- AI Agent collaboration (#VirtuosoRDBMS Support Assistant, Data Twingler Assistant, etc.)
- Supported LLM listing & Use
Introducing the OpenLink AI Layer (OPAL) MCP Server
1/ This MCP Server is a game-changer for loosely coupling AI Agents & Data Spaces (databases, knowledge graphs, filesystems) coupling.
The EU (across many key projects) has been one of our major customers—successfully rolling out and expanding their use of #VirtuosoRDBMS for over a decade.

We've just published a community post showcasing the power of the OpenLink AI Layer (OPAL) in action. It includes Cello, an AI Agent prototype built using the EU's Virtuoso-based SPARQL endpoint.
Attached is a simple MCP demo using the new mcp-odbc-server with our multi-model Virtuoso platform for data access, integration, and management. #MCP #ODBC #VirtuosoRDBMS #SQL #SPARQL #DataConnectivity #LinkedData #HowTo
We’re excited to introduce the latest Virtuoso Maintenance Release—Virtuoso 08.03.3333—packed with feature enhancements and bug fixes across the platform.

One of #VirtuosoRDBMS’s many superpowers is its ability to emit HTML directly from its DBMS core—unlike PHP, JSP, or ASP, where HTML generation happens separately. With native HTTP support, Virtuoso handles this seamlessly for powerful, data-driven web applications!
Here’s a DataTwingler AI Agent configuration in Markdown, designed for interacting with UniProt’s massive Knowledge Graph, which consists of 210 billion machine-computable statements of fact, meticulously curated by domain experts.
https://github.com/OpenLinkSoftware/Assistants/blob/main/data-twingler-uniprot.md
This AI Agent enables scalable, explainable, and verifiable AI interactions with UniProt’s Knowledge Graph, seamlessly integrating LLMs with high-quality biomedical data via its #VirtuosoRDBMS-based SPARQL query services endpoint.
Whoa! UniProt’s latest publicly accessible Knowledge Graph now contains 210,122,358,019 RDF triples—powered by our #VirtuosoRDBMS open-source edition, live on the Web and available to AI Agents, Apps and Services across life sciences, genomics, bioinformatics, and related fields. #KnowledgeGraph
