Using MCP on your DKG Node

How does the DKG work with MCP?

By registering the DKG as a tool provider in an MCP server, you can:

• Query knowledge using tools like query_dkg_by_name, which execute SPARQL queries over the DKG

• Publish knowledge from unstructured text using tools like create_knowledge_asset, which turn LLM-generated content into structured JSON-LD and publish it to the DKG

• Expand the tools above and add additional tools to interact with the DKG (e.g. creating Knowledge Assets from websites or documents)

This allows agents using MCP-compatible clients to:

• Interact with real-time, decentralized knowledge

• Add to the shared memory layer used by other agents

• Benefit from data provenance, versioning, and ownership built into the DKG

Why is this powerful?

MCP makes it easy to build modular, agent-based systems where LLMs use tools to:

• Ask questions against the Decentralized Knowledge Graph

• Write and revise their own memory as JSON-LD Knowledge Assets

• Store results and publish new discoveries collaboratively

When paired with the DKG, this gives LLM-based systems access to a decentralized knowledge base that is:

• Interoperable (via RDF and schema.org)

• Trustworthy (anchored with cryptographic proofs)

• Queryable (via SPARQL and linked data tooling)

To get started:

• Explore the dkg-mcp-server example repo

• Try integrating the DKG into your MCP server

• Build agents that reason over, expand, and query the decentralized web of knowledge
