The Missing Protocol: How MCP Bridges LLMs and Data Streams
summary
Claims that MCP turns LLMs into first‑class participants in streaming architectures by exposing Kafka and other systems as callable tools. The demo wires an MCP client to an MCP server that reads and writes Kafka topics, lists clusters/connectors/topics, and returns JSON summaries; it uses JSON‑RPC MCP server endpoints and integrates with frameworks like Spring AI and langchain4j. The prototype runs live, produces JSON messages back into topics, and warns that adding many tools pollutes context windows and requires careful scope and context management.
