Agent Skills: Maven Tools

JVM dependency intelligence via Maven Tools MCP server. Use when user asks about Java/Kotlin/Scala dependencies, versions, upgrades, CVEs, or licenses. Use when analyzing pom.xml, build.gradle, or any Maven Central dependency. Use when user says 'check my dependencies', 'should I upgrade X', 'is this version safe', or 'what's the latest version of Y'.

Maven Tools

Dependency intelligence for JVM projects via Maven Tools MCP server.

Prerequisites

Requires Maven Tools MCP server configured in your MCP client.

Recommended setup (Claude Desktop):

{
  "mcpServers": {
    "maven-tools": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "arvindand/maven-tools-mcp:latest-noc7"]
    }
  }
}

Why -noc7? The latest-noc7 variant focuses purely on dependency intelligence. For documentation lookup, use the separate context7 skill which provides broader coverage and works independently. This modular approach means dependency tools work even if Context7 is blocked.

When to Use

Activate automatically when:

  • User asks about Java/Kotlin/Scala/JVM dependencies
  • User mentions Maven, Gradle, pom.xml, build.gradle
  • User asks "what's the latest version of X"
  • User wants to check for updates, CVEs, or license issues
  • User says "analyze my dependencies" or "check my pom.xml"
  • User asks "should I upgrade X" or "is this version safe"

Tool Selection

Pick the right tool for the task (8 tools available):

| User Intent | Tool | Key Parameters | |-------------|------|----------------| | "Latest version of X" | get_latest_version | stabilityFilter: PREFER_STABLE (default) | | "Does version X.Y.Z exist?" | check_version_exists | — | | "Check these dependencies" (no versions) | check_multiple_dependencies | stabilityFilter | | "Should I upgrade from X to Y?" | compare_dependency_versions | includeSecurityScan: true | | "How old are my dependencies?" | analyze_dependency_age | maxAgeInDays threshold | | "Is this library maintained?" | analyze_release_patterns | monthsToAnalyze: 24 | | "Show version history" | get_version_timeline | versionCount: 20 | | "Full health check" | analyze_project_health | includeSecurityScan, includeLicenseScan |

Default choice: When user says "check my dependencies" or pastes a pom.xml → use analyze_project_health for comprehensive analysis.

Stability Filters

Control which versions are returned:

| Filter | Use When | |--------|----------| | PREFER_STABLE | Default for recommendations — prioritizes stable, includes others | | STABLE_ONLY | Production upgrades — no RC/beta/alpha | | ALL | Research — see everything including snapshots |

Common Workflows

"Check my dependencies"

  1. Extract dependencies from pom.xml or user input
  2. Call analyze_project_health with:
    • includeSecurityScan: true
    • includeLicenseScan: true
  3. Report: outdated deps, CVEs, license risks, health score

"Should I upgrade Spring Boot?"

  1. Call compare_dependency_versions with current and target versions
  2. If major upgrade detected, note breaking changes likely
  3. Use Context7 tools for migration documentation:
    • resolve-library-id with "spring boot migration"
    • query-docs with returned ID

"Is this dependency safe?"

  1. Call get_latest_version to check if user's version is current
  2. Call analyze_release_patterns to verify active maintenance
  3. Security scan is included by default — report any CVEs

"What libraries should I use for X?"

  1. This tool doesn't recommend new libraries — it analyzes existing ones
  2. Suggest user specify candidate libraries
  3. Then use analyze_project_health to compare candidates

Dependency Format

All tools expect Maven coordinates:

groupId:artifactId

Examples:

  • org.springframework.boot:spring-boot-starter
  • com.fasterxml.jackson.core:jackson-databind
  • org.junit.jupiter:junit-jupiter

From Gradle: Convert implementation("group:artifact:version") → group:artifact

Documentation Lookup (Guided Delegation)

Maven Tools provides version intelligence. For migration guides and API documentation, delegate to the context7 skill.

Workflow:

  1. Maven analysis reveals upgrade needed (e.g., Spring Boot 2→3)
  2. Load context7 skill for documentation lookup
  3. Query: "spring boot 3 migration guide" or "hibernate 6 breaking changes"
  4. Combine version data + documentation for complete upgrade plan

Example chain:

User: "Should I upgrade Spring Boot from 2.7 to 3.2?"

→ maven-tools: compare_dependency_versions
  Result: Major upgrade, 3.2.1 available, no CVEs

→ context7: resolve_library_id("spring boot")
→ context7: get_docs(id, "2.7 to 3 migration guide")
  Result: javax→jakarta migration steps, config changes

→ Combined response: Version analysis + migration steps

This separation means:

  • Dependency tools work even if Context7 is unreachable
  • Context7 skill is reusable for any library, not just JVM
  • Each skill stays focused and maintainable

Response Interpretation

Health Scores

| Score | Meaning | |-------|---------| | 80-100 | Healthy — recent releases, no CVEs | | 60-79 | Good — minor concerns | | 40-59 | Aging — consider updates | | 0-39 | Stale — maintenance risk |

Age Classification

| Class | Age | Action | |-------|-----|--------| | fresh | <6 months | No action needed | | current | 6-12 months | Monitor | | aging | 1-2 years | Plan upgrade | | stale | >2 years | Upgrade or replace |

Version Types

| Type | Production Safe? | |------|-----------------| | stable | ✅ Yes | | rc | ⚠️ Test thoroughly | | beta | ⚠️ Non-critical only | | alpha | ❌ Development only | | milestone | ⚠️ Early adopters | | snapshot | ❌ Never in production |

Examples

Example 1: Quick version check

User: "What's the latest stable Spring Boot?"

→ get_latest_version
  groupId: org.springframework.boot
  artifactId: spring-boot-starter
  stabilityFilter: STABLE_ONLY

Example 2: Upgrade analysis

User: "I'm on Spring Boot 2.7.18, should I upgrade?"

→ compare_dependency_versions
  dependencies: ["org.springframework.boot:spring-boot-starter:2.7.18"]
  includeSecurityScan: true

→ If major upgrade available, delegate to context7 skill:
  resolve_library_id("spring boot")
  get_docs(id, "2.7 to 3 migration guide")

Example 3: Full project audit

User: "Analyze my pom.xml" (pastes file)

→ Extract all dependencies from pom.xml
→ analyze_project_health
  dependencies: [extracted list]
  includeSecurityScan: true
  includeLicenseScan: true

Recovery

| Issue | Action | |-------|--------| | Dependency not found | Verify groupId:artifactId format, check Maven Central | | Context7 skill unavailable | Fall back to web search for documentation | | Security scan slow | Results still return, CVE data may be partial | | Unknown version type | Treat as unstable, recommend stable alternative |
