Pulse watches the traffic flowing through MCP servers

Why it surfaced

The product has a crisp one-line installation story and an unusually concrete data boundary: its schema records tool names, client versions, durations, statuses, and salted session hashes, but has no fields for prompts, arguments, results, IP addresses, or error messages. It also turns server activity into live dashboards, README badges, and public stats pages.

Pulse is a privacy-focused analytics tool for Model Context Protocol servers, tracking clients, tool calls, latency, and error classes without collecting payloads.
