spring-mosaic is an MCP server that reviews Java/Spring Boot/PostgreSQL repositories against organizational standards, delivering structured and actionable feedback.

• Detect Spring context (detect_spring_context): Identify Spring Boot/Java version, build tool (Maven/Gradle), and module structure.

• Explore quality domains (list_quality_domains): List all available Java/Spring quality domains.

• Retrieve quality guides (get_quality_guide): Access detailed standards for domains including architecture, spring-boot, rest-api, data-jpa, security, testing, performance, anti-patterns, review-format, scaffolding, modernization, and git-conventions.

• Deep-dive into patterns (explain_pattern): Get in-depth explanations on topics like JPA, REST DTOs, constructor injection, or Boot 3 migration.

• Generate PR review brief (get_pr_review_brief): Obtain minimal review format and common anti-patterns.

• Get diff-relevant sections (get_review_sections_for_diff): Return quality guide sections relevant to changed file extensions (e.g., .java, .yml).

• Orchestrate full PR review (review_pr_diff): Produce a step-by-step review plan based on changed files with extension-specific guidance.

• Audit files/workspace (audit_changed_files, audit_workspace): Provide structured feedback on a set of changed files or an entire directory.

• Review architecture (review_architecture): Execute a layer-by-layer architecture checklist on Java/Spring diffs.

• Scan for anti-patterns (scan_violations): Heuristic scan of a single Java/Kotlin file for common Spring violations.

• Setup tool (spring-mosaic-setup): Automatically wire the server into a Java repository (Cursor/Cline compatible).

Provides tools for reviewing Java/Spring architecture, quality, and PR diffs, including detecting Spring context, listing quality domains, explaining patterns, scanning for anti-patterns, and reviewing architecture layer checklist.

Specifically focused on Spring Boot, providing context detection (Boot version), quality guides, and review tools for Spring Boot projects.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@spring-mosaic Review PR diff for Spring Boot anti-patterns"

That's it! The server will respond to your query, and you can continue using it as needed.
