MCP server uptime analysis reveals bimodal reliability, not a spectrum

By PulseAugur Editorial · [1 sources] ·

Analysis of MCP server uptime reveals that reliability is not a spectrum but rather bimodal, with a large majority of servers being consistently available and a small fraction being entirely unresponsive. The study tracked 400 MCP endpoints daily for a month, finding that approximately 78% of servers never missed a day of uptime. Conversely, about 5.5% of servers never answered any probes, and a closer examination suggests that less than 3% of these might be genuinely defunct, with others refusing anonymous requests. Furthermore, a single-day snapshot of server status can overstate persistent failures by as much as 24%, as many failures are transient. AI

    MCP server uptime isn't a spectrum: 78% never miss a day, 5.5% never answer

    <p>Everyone quotes MCP server health as one number. I have been quoting one too: about 92% of a fixed set of servers answer on any given day.</p> <p>That number is real and it is also useless, because there is no server that behaves like it. I probed the same 400 MCP endpoints ev…
