AppDynamics Server

A Model Context Protocol server that gives LLM clients (Cursor, Claude Desktop, etc.) full access to your AppDynamics monitoring data — plus the ability to create and manage dashboards and health rules.

Features

30 tools across 8 categories:

• Discovery: List and search applications by name
• Health Monitoring: Full health rule CRUD, violations, and anomaly detection
• Application Performance: Business transactions, service endpoints, and their metrics
• Infrastructure: Tiers, nodes, and backend/remote service dependencies
• Diagnostics: Transaction snapshots and error events
• Root Cause Analysis: Automated composite diagnosis across all signal types
• Metrics: Browse the metric tree and query any metric with rollup support
• Dashboards: Full CRUD — list, view, create, update, add widgets, clone, delete, export, import, auto-build, per-rule health status widgets

Key capabilities

• Natural language friendly: Accept application names, not just IDs
• Metric tree browser: Discover available metrics interactively, including custom/machine-agent metrics
• Rollup control: Per-widget rollup for time-series vs. aggregate metric views
• Dashboard auto-builder: Create full multi-section dashboards from a single prompt
• HealthListWidget scoping: Each widget can be pinned to a specific health rule (not "all rules")
• Health rule CRUD: Create, update, enable/disable, and delete health rules — including custom metrics scoped to a specific tier or node
• Smart defaults: Sensible time ranges and result limits out of the box

appd_create_dashboard	Create a new dashboard with optional widgets
appd_update_dashboard	Update dashboard properties and/or widgets

Dashboard widget types

Widget type	Description
TIMESERIES_GRAPH	Time-series line chart for one or more metrics
METRIC_VALUE	Single aggregated number (gauge tile)
GAUGE	Gauge dial
PIE	Pie chart
HEALTH_LIST	Health rule status list. Set healthRuleIds: [id] to pin a widget to a specific health rule instead of showing all rules for the application.
TEXT	Static text / label

Example Conversations

"What's the health status of my production apps?" → Uses appd_get_applications + appd_get_health_violations + appd_get_anomalies

"Show me the slowest business transactions for the Orders app" → Uses appd_get_business_transactions + appd_get_bt_performance

"What databases does the Payment service connect to?" → Uses appd_get_backends with typeFilter="JDBC"

"Create a health rule that fires when Custom Metrics|RequestCount > 1000 on the WebTier" → Uses appd_create_health_rule with affectedEntityType="TIER_NODE_HEALTH", affectedTier="WebTier", metricPath="Custom Metrics|RequestCount"

"Create a dashboard for the Checkout app with response time and error rate" → Uses appd_get_applications → appd_browse_metric_tree → appd_create_dashboard

"Build me a full monitoring dashboard for the Orders app" → Uses appd_auto_build_dashboard — auto-discovers all tiers, BTs, and health rules, creates a complete dashboard in one shot

"Create one health widget per URL Monitor service, each scoped to its own rule" → Uses appd_create_health_rule (one per service) + appd_create_dashboard with healthRuleIds on each HEALTH_LIST widget

"Clone the production monitoring dashboard for staging" → Uses appd_get_dashboards → appd_clone_dashboard

"Why is my Payment app slow? Diagnose the last hour" → Uses appd_diagnose_issue with application="Payment", durationInMins=60 — returns ranked root cause candidates, merged event timeline, error class breakdown, and step-by-step investigation guide

"Are there any errors spiking in the Orders app right now?" → Uses appd_diagnose_issue with application="Orders", focus="errors"

Health Rules — Custom Metrics

Custom metrics reported by machine agents are stored per-node under:

Application Infrastructure Performance|{Tier}|Individual Nodes|{Node}|Custom Metrics|{MetricName}

When creating health rules for custom metrics, use affectedEntityType=TIER_NODE_HEALTH and provide the relative metric path (not the full absolute path):

affectedEntityType: "TIER_NODE_HEALTH"
affectedNode: "my-server-hostname"          # scope to specific node
metricPath: "Custom Metrics|MyMetric"       # relative path only

Development

# Run in dev mode (auto-reload)
npm run dev

# Build TypeScript
npm run build

# Run built version
npm start

Authentication

The server supports two authentication modes:

1. OAuth2 Client Credentials (recommended): Set APPD_CLIENT_NAME, APPD_CLIENT_SECRET, and optionally APPD_ACCOUNT_NAME. The server acquires and caches tokens automatically.

2. API Key: Set only APPD_CLIENT_NAME (as the API key). No secret needed.
