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.
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.
Transparent proxy for any MCP server that intercepts all JSON-RPC messages, measures latency, and stores traces in SQLite, PostgreSQL, or MySQL. Exports OpenTelemetry (OTLP) spans to Jaeger, Tempo, or Grafana. Supports stdio, HTTP, and SSE transports. npx @cardor/heimdall-mcp
