MCP Server Logs Show Only Crawlers: 60 Bots, Zero Real Agent Sessions
ChiefGrowth · reddit · 2026-08-28
Analysis of 24 hours of traffic from a public MCP server revealed 6,309 requests from 187 user agents, but zero sessions resembling actual agent work.
Traffic Breakdown:
- 60 named crawlers: 14 liveness monitors, 16 directory indexers, 9 ecosystem probes, and 5 security researchers.
- 1,545 POST requests were all health checks or directory ingests (initialize/tools/list), with no actual tool invocations.
Key Observations:
- The ecosystem is crowded with monitoring services (14 detected).
- Many crawlers self-disclose behavior in User-Agent strings (e.g., "liveness-only"), aiding classification.
The author published the dataset and a regex matcher for others to analyze their logs, questioning if "all traffic is monitors" is a universal trend.
