Spring Tools 5.2.0 Adds Experimental Claude Code Plugin and Spring AI Support

Key Takeaways

  • Spring Tools 5.2.0 introduces an experimental Claude Code Plugin that feeds an AI coding assistant live, IDE-sourced Spring project data through an embedded MCP server, giving the model access to classpath, bean graph, and diagnostic information that generic code analysis cannot provide.
  • The MCP server is IDE-resident by design: it requires the project to be open in a Spring Tools-powered environment and does not function as a standalone service, which limits its use to workflows where a supported IDE and a CLI-based agent run in parallel.
  • First-class Spring AI support and a type-safe property refactoring feature extend the tooling to two areas of active Spring ecosystem development, making 5.2.0 a meaningful update for teams building AI-integrated Spring applications.

Broadcom's Spring Tools team released version 5.2.0 of its IDE tooling suite on June 15, adding an experimental plugin for Claude Code, Anthropic's command-line AI coding agent, alongside a bundle of new developer productivity features and an upgrade to Eclipse 2026-06.

The headline addition is the Claude Code Plugin, which the team explicitly marked as experimental and in early access. The plugin provides two components: an embedded Model Context Protocol (MCP) server and a set of Claude Code skills. The MCP server exposes Spring-specific static project analytics to the language model, including resolved classpaths, Spring Boot version information, bean dependency graphs, component stereotypes, and Spring-specific problem reports with suggested fixes. The skills guide Claude Code on when and how to query the embedded server in a Spring project. Because the Spring Tools MCP server runs inside the IDE and draws its data from the active workspace, it cannot be used in isolation: developers using Claude Code from a terminal must have their project open in a Spring Tools-powered IDE concurrently.

The release notes state that the Spring Tools project "does not ship its own large language model and does not require you to authenticate against a specific LLM provider. The integration happens purely via the existing AI coding assistants that you have configured." The same embedded MCP server is also available to GitHub Copilot users in Eclipse-based environments, where it is configured automatically upon Copilot detection.

Beyond the Claude Code integration, Spring Tools 5.2.0 adds general support for Spring AI, extending IDE-level assistance to projects that use the framework. A type-safe property references feature allows developers to refactor string-based configuration property references into type-safe ones and handles multiple simultaneous references. The release also brings Maven repository-based version validation with a quick-fix action to update dependencies to the latest patch version, improvements to the Spring Indexer and the ahead-of-time compilation cache for JDK 25, and a regression fix for the Add New Starter action in the Eclipse distribution, which had stopped modifying <code>pom.xml</code> files correctly.

The next scheduled release, Spring Tools 5.3.0, is planned for mid-September 2026.
