An MCP server that analyzes Spring Boot Actuator endpoints — health, metrics, environment, beans, startup, and caches. Detects issues, security risks, and provides actionable recommendations.

There is no other MCP server that analyzes Spring Boot Actuator endpoints. This is the only tool that lets your AI assistant understand your Spring Boot application's health, performance, configuration, and startup behavior through actuator data.

7 analytical tools turn raw actuator JSON into actionable diagnostics — health checks, JVM metrics analysis, security risk detection in environment/beans, startup bottleneck identification, and cache efficiency analysis.

Parse and diagnose the /health endpoint response. Detects unhealthy components (database, Redis, Kafka, Elasticsearch, disk space) with component-specific recommendations.

curl http://localhost:8080/actuator/health | jq '.' > health.json

Detects:

• DOWN/OUT_OF_SERVICE components
• Low disk space warnings (< 15% free)
• Nested component health (e.g., primary/secondary databases)
• Restricted health endpoints (no show-details)

Analyze JVM, HTTP, and database pool metrics from /metrics endpoints.

# Collect metrics into a single JSON object:
{
  "jvm.memory.used": 800000000,
  "jvm.memory.max": 1000000000,
  "jvm.threads.live": 150,
  "jvm.gc.pause.count": 500,
  "jvm.gc.pause.total": 8.5,
  "http.server.requests.count": 10000,
  "http.server.requests.error.count": 50,
  "hikaricp.connections.active": 8,
  "hikaricp.connections.max": 10
}

Detects:

• Heap utilization >= 90% (CRITICAL) or > 75% (WARNING)
• High thread count (> 500)
• Long GC pauses
