MCP Dashboard

Once you've configured the Sentry SDK for your MCP project, you'll start receiving data in the Sentry MCP Insights dashboard.

The main dashboard provides a comprehensive view of all your MCP server activities, performance metrics, and recent tool executions.

The dashboard displays key widgets like:

• Traffic: Shows MCP requests over time, error rates, and releases to track overall server activity and health
• Traffic by Client: Displays which MCP clients are connecting to your server (cursor-vscode, CustomMCPClient, etc.)
• Transport Distribution: Shows the distribution of transport protocols used (http, sse, custom transports)
• Most Used Tools/Resources/Prompts: Shows which MCP tools/resources/prompts are called most frequently by clients
• Slowest Tools/Resources/Prompts: Identifies tools/resources/prompts with the highest response times for performance optimization
• Most Failing Tools/Resources/Prompts: Highlights tools/resources/propmpts with the highest error rates that need attention

Underneath these widgets are tables that allow you to view data in more detail:

• Tools: Performance metrics for each MCP tool including request count, error rate, average duration, and P95 latency
• Resources: Access patterns and performance for MCP resources by URI, showing requests, error rate, average duration, and P95 latency
• Prompts: Usage statistics for MCP prompt templates by name, including requests, error rate, average duration, and P95 latency
