The first comprehensive analysis of MCP server reliability across 615+ monitored servers. Real data, no marketing fluff.
We analyzed 615 MCP servers over the past 30 days, performing 1.7M health checks. The average reliability score across all servers is 54.4%, indicating room for improvement across the ecosystem.
These servers demonstrated exceptional uptime and performance over the past 30 days.
These servers experienced significant reliability issues. Server operators should investigate.
Surprisingly, community-maintained MCP servers showed Infinity% higher average reliability scores compared to official servers. This suggests active community maintenance and monitoring leads to better reliability outcomes.
Most servers cluster into two groups: ultra-fast (<100ms) or slow (>500ms). The middle ground is rare. This indicates architecture matters more than incremental optimization.
0.0% of failures were timeouts, not server errors. This suggests network configuration and timeout tuning should be a priority for MCP server operators.
Servers with active MCPulse monitoring showed 15-20% fewer incidents over time. Visibility drives accountability and faster incident response.

This report is based on real production data from MCPulse's monitoring infrastructure. We do not simulate or extrapolate—every metric comes from actual health checks performed against live MCP servers.
Reliability scores are calculated using a weighted formula that considers:
All data in this report is accessible via our public server directory and API. We believe reliability data should be open and verifiable.
