MCP Tools	mcp_azure_mcp_eventhubs, mcp_azure_mcp_servicebus
Best For	Diagnosing SDK connection, auth, and message processing issues

When to Use This Skill

• SDK connection failures, auth errors, or AMQP link errors
• Idle timeout, connection inactivity, or slow reconnection after disconnect
• AMQP link detach or detach-forced errors
• Message lock lost, message lock expired, lock renewal failures, or batch lock timeouts
• Session lock lost, session lock expired, or session receiver errors
• Event processor or message handler stops processing
• Duplicate events or checkpoint offset resets
• SDK configuration questions (retry, prefetch, batch size, receive batch behavior)

MCP Tools

Tool	Command	Use
mcp_azure_mcp_eventhubs	Namespace/hub ops	List namespaces, hubs, consumer groups
mcp_azure_mcp_servicebus	Queue/topic ops	List namespaces, queues, topics, subscriptions
mcp_azure_mcp_monitor	logs_query	Query diagnostic logs with KQL
mcp_azure_mcp_resourcehealth	get	Check service health status

Diagnosis Workflow

1. Identify the SDK and version — Check the prompt for SDK and version clues; if not stated, proceed with diagnosis and ask later if needed
2. Check resource health — Use mcp_azure_mcp_resourcehealth to verify the namespace is healthy
3. Review the error message — Match against language-specific troubleshooting guide
4. Look up documentation — Use mcp_azure_mcp_documentation to search Microsoft Learn for the error or topic
5. Check configuration — Verify connection string, entity name, consumer group
6. Recommend fix — Apply remediation, citing documentation found
