Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Query Spanlens LLM observability from Claude Desktop, Cursor, or Continue: request logs, costs, agent traces, anomalies, and user analytics with a read-only API key.
Socket.IO-style telemetry for MCP servers. Instrument a tool call with a few lines of mcp-telemetry-sdk, and telemetrysubscribe streams its live progress (steps, logs, cost, done) to any connected MCP client via notifications/progress — no polling, and a job started in one session can be watched from a completely different one.
