spring-mosaic
MCP server for Java/Spring Boot architecture quality analysis and PR review, providing tools like detect_spring_context, review_pr_diff, and scan_violations.
README
spring-mosaic
MCP server for Java / Spring Boot architecture, API quality, and PR review — the sibling of ai-mosaic (Angular).
Same protocol and Cursor wiring as ai-mosaic; different domain (JVM / Spring).
Naming
| Name | Notes |
|---|---|
| spring-mosaic (chosen) | Pairs with ai-mosaic; clear Spring focus |
java-mosaic |
Broader JVM (Java/Kotlin) without Boot emphasis |
boot-mosaic |
Boot-only branding |
mosaic-jvm |
Family name for all JVM backends |
Published on GitHub Packages (same pattern as @himakarinv-stack/ai-mosaic).

Tools
| Tool | Purpose |
|---|---|
detect_spring_context |
Boot/Java version, Maven/Gradle, modules |
list_quality_domains |
Domain index |
get_quality_guide |
One standards section (spring-boot is boot2/boot3 aware) |
explain_pattern |
Topic deep-dive |
get_pr_review_brief |
Review format + anti-patterns |
get_review_sections_for_diff |
Sections for changed extensions |
review_pr_diff |
PR orchestration plan |
review_architecture |
Layer checklist |
scan_violations |
Heuristic Java/Spring anti-pattern scan |
Suggested PR workflow
detect_spring_context → get_pr_review_brief → review_pr_diff
→ scan_violations (per file) → review_architecture
Note on implementation language
This package is a Node MCP server (like ai-mosaic) that teaches and reviews Java/Spring code. A native Spring Boot MCP (Spring AI starters) is optional later if you want HTTP-deployed tools; Cursor STDIO works best with this layout today.
