Maven Tools

Maven Tools

Use this skill to ground JVM dependency decisions in live Maven Central data.

This is an execution skill. Use Maven Tools MCP first for dependency facts, then do the reasoning in-model. Assume Maven Tools MCP is already configured; only discuss setup if the tools are unavailable.

When to Use

Activate when the user asks about:

• Java, Kotlin, Scala, or JVM dependencies
• Maven, Gradle, pom.xml, build.gradle, or build.gradle.kts
• latest versions, upgrades, CVEs, licenses, dependency age, or release history
• whether a dependency is safe, current, stale, or worth upgrading

Core Boundary

Use Maven Tools MCP for version, security, license, freshness, and release-pattern facts from Maven Central.

• Do the reasoning in-model: recommend next steps, call out risk, and separate safe-now actions from manual-review items.
• Normalize dependency inputs to groupId:artifactId or groupId:artifactId:version as needed.
• For recommendation questions, evaluate concrete candidates with Maven Tools first, then add documentation context before making a strong call.
• Do not use Maven metadata alone to decide library popularity, framework fit, migration effort, or performance tradeoffs.

Tool Selection

Choose the narrowest tool that matches the request:

Default to analyze_project_health when the user says "check my dependencies" or pastes a project dependency set.

Use check_multiple_dependencies for candidate sets without current versions. Use compare_dependency_versions for upgrade decisions on current versions. Use analyze_project_health for broad audits, not every single dependency question.

Workflow

1. Extract dependencies from user input or the build file
2. Pick the narrowest tool that answers the request
3. Report the result in decision-oriented language:
   • what is current
   • what changed
   • what is safe to do now
   • what needs manual review

For upgrade questions, prefer compare_dependency_versions with:

• includeSecurityScan: true
• stabilityFilter: STABLE_ONLY

Then interpret the result conservatively:

• patch and minor updates are the default safe path
• major updates should be treated as manual review unless the user explicitly wants a breaking upgrade

When compare_dependency_versions returns same_major_stable_fallback:

• treat the top-level major upgrade as the long-term path
• treat the fallback as the safest immediate upgrade target
• surface both, but recommend the fallback first for conservative maintenance workflows

This is especially important for "safe update" or bot-like maintenance flows.

If the user asks whether a dependency is safe:

1. use compare_dependency_versions when remediation guidance matters
2. use analyze_release_patterns when maintenance risk matters
3. combine the two instead of relying only on "latest version" checks

Documentation Handoff

When the answer needs migration guides, API details, or library usage patterns, add documentation context before giving a strong recommendation.

Use this order:

1. use Maven Tools MCP first for dependency facts
2. if raw Context7 tools are available in the current tool list, use them directly
3. otherwise, if standalone Context7 tools are available, use them
4. otherwise, use WebSearch and WebFetch for official docs, release notes, and migration guides
5. if no documentation path is available, say dependency facts are available but deeper doc lookup is not

Use this especially for:

• major upgrades
• migration planning
• recommendation-style comparisons between candidate libraries

Less Helpful / Out of Scope

• private artifact repositories that are not mirrored through Maven Central
• non-JVM ecosystems that do not use Maven coordinates
• trivial one-off lookups where the exact dependency and decision are already obvious
• recommendation questions driven mostly by ecosystem adoption or benchmarks unless you also add docs and broader research

Setup Assumption

Assume the user already has Maven Tools MCP configured.

• arvindand/maven-tools-mcp:latest is the default when raw Context7 tools should be exposed through the same server
• arvindand/maven-tools-mcp:latest-noc7 is the clean option when documentation is handled separately

Only discuss installation when the tools are unavailable.
