Micronaut Fun

Micronaut Fun is an MCP server that provides AI coding assistants with searchable access to official Micronaut framework documentation and guides. Built on the Micronaut framework and OpenSearch, the service exposes documentation sets as structured MCP resources, delivers search tools, and provides purpose-built prompts for common development workflows. Software engineers developing Java, Kotlin, or Groovy applications use this server to retrieve current framework guidelines, API references, and architecture standards without leaving their coding environments. By bridging the Model Context Protocol with the remote search backend, it enables AI clients to locate exact documentation sections, suggest idiomatic configurations, write unit and integration tests aligned with Micronaut standards, and inspect guides for cloud-native deployment. Users can connect through hosted endpoints or self-host the application using Gradle and Docker to inspect custom search indexes locally.

How to install and configure Micronaut Fun

To integrate Micronaut Fun with your MCP client, configure the remote server endpoint: 1. Ensure your MCP client supports remote Model Context Protocol connections. 2. Add the remote server URL https://micronaut.fun/mcp to your client configuration file, such as Claude Desktop, Claude Code, Cline, VS Code, or IntelliJ IDEA with GitHub Copilot. 3. Save the configuration and restart your client application. 4. For running the service locally, clone the repository and run ./gradlew run. If using OpenSearch, launch the container using docker run -d --name micronautfunopensearch -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" -e "plugins.security.disabled=true" -e "OPENSEARCH_INITIAL_ADMIN_PASSWORD=DummyPassword#1233" opensearchproject/opensearch:2.19.3 and adjust configuration properties as described in the repository README at https://github.com/micronaut-projects/micronaut-fun.

What you can do with Micronaut Fun

• Searching Micronaut documentation and official guides directly within your IDE to reference framework modules and configuration parameters. - Loading official Micronaut guide resources into AI conversational context to verify best practices for dependency injection and controllers. - Generating idiomatic unit and integration tests for Micronaut microservices using preconfigured prompts tailored to standard testing conventions. - Resolving cloud-native configuration issues by querying search tools against up-to-date documentation on security, datasources, and messaging modules.
