DevRel newsletter — October 2025
Blog post from Elastic
The October 2025 Elastic DevRel newsletter highlights the new Agent Builder feature in Elasticsearch, which integrates with Kibana to enable users to transform ES|QL queries into reusable tools and organize them into agents capable of solving multistep tasks. Although still in preview, the feature leverages the Model Context Protocol (MCP) to allow seamless integration with MCP-compatible clients, offering flexibility beyond Kibana. The newsletter also introduces Kibana’s new natural-language conversation interface, where Elastic Inference Service (EIS) can process queries using the appropriate tools. It details various resources, including free on-demand training, blogs, and videos that explore topics such as context engineering, vector search, and retrieval-augmented generation (RAG) solutions. Upcoming Elastic events are announced, including Elastic{ON} Tour, which will occur in major cities worldwide, focusing on AI and security. The newsletter encourages community participation and submissions for presentations at these events, emphasizing Elastic's commitment to fostering collaboration and innovation within its community.
