LLMs + the Model Context Protocol (MCP) are the Yang to the Semantic Web Project's Yin.

We now have a solution to the final hurdle—visualization.

Years of Linked Data work now come alive. I explain this, with demonstrations, in a new newsletter post.

One more thing, OPAL implements MCP as both a Client and Server, so it can bind to operations (tools) published by other MCP Servers that support SSE or Streamable HTTP.

Links in the next reply for a quick example.

🧰 This is what modern AI infrastructure looks like.

Here’s a quick showcase featuring AnthropicAI’s Claude Desktop interacting with a live OPAL instance that queries the DBpedia Knowledge Graph—entirely instructed using natural language.

⚙️ Deploying to the cloud? It’s simple:

1. Go to the AWS Marketplace
2. Instantiate the OPAL AMI
3. Open {cname}/chat and log in
4. Plug in your favorite LLM API key from providers

Enjoy!

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 happening here?

An A2A Orchestrator is interacting with an LLM-powered AI Agent that exposes procedures, functions, 3rd party APIs etc., as MCP-accessible tools.

All made possible by the, in deceptively simple manner, by the OpenLink AI Layer (OPAL).

Do you have a link to a doc about how to setup Remote MCP Servers that support OAuth or Bearer Token based authentication?

Right now, you aren’t handling 401’s that trigger the OAuth handshake and I don’t know what you support regarding Authentication Headers.

The Model Context Protocol (MCP) brings Unix-style loose coupling to AI Agents.

I built a visual explainer (JSON-LD metadata included) using Google Gemini’s new Canvas feature—with an embedded Knowledge Graph to illustrate.

Check it out:

Kingsley Uyi Idehen @kidehen.bsky.social · May 29

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.

BTW -- @Google Gemini can generate pretty accurate diagrams using @drawio XML!

It's been a while!

BTW -- I am working pretty extensively on MCP right now, so I would certainly like to have a play with Xogot.

Is there a repo link?

No, but a link-relation would be a neat addition to the spec since centralized registries will never solve the discovery problem.

The following should do.

I'll propose it :)

What a journey it’s been—starting with the ambitions of CORBA, the data connectivity standards of ODBC and JDBC, the global reach of the Web, and now, in the age of AI, it all converges through the Model Context Protocol (MCP).

Yes—if the MCP servers support Server-Sent Events (SSE) or Streamable HTTP, it’s possible. The main challenge right now is that most MCP clients are still STDIO-based, primarily due to lagging implementation of OAuth 2.1 for authentication.

Kingsley Uyi Idehen @kidehen.bsky.social · May 20

Very interesting stuff will happen, as demonstrated by the sheer number of MCP Servers. On our part, we offer MCPs for the following database connectivity protocols:

1. ODBC
2. JDBC
3. pyODBC
4. ADO.NET

Why?
To reintroduce DBMS independence in the age of AI :)

Yep!

DNS – Enables scalable machine name lookups across the Internet.

HTTP – Enables lookups of entities, their types, and their relationships at Web scale—where the Web serves as an abstraction layer over the Internet.

MCP – Enables access to tools (functions, operations) at Web scale.
