- Logs record events; APM watches performance; neither explains behavior.
- APM treats a 200 as success, so tool errors slip past it.
- MCP analytics reads the protocol: clients, tools, and completions.
Teams often assume their existing observability already covers the MCP server. It covers part of it. Understanding where each layer stops makes the gap obvious.
Server logs
Logs record what happened: a request arrived, a response left. They are complete and low-level, and they say nothing about behavior, outcomes, or which agent did what.
APM and tracing
APM watches performance: latency, throughput, traces across services. It was built for human and service traffic. It treats a 200 as success, so tool errors inside a 200 slip past it.
MCP analytics
This layer reads the protocol: who connected, which tools they used, whether workflows completed, and what to fix. It is the analytics layer agents need, the same way websites needed one on top of raw logs.
Logs recorded it. APM watched it. Neither explained it.
You likely want all three. But only the analytics layer answers the questions a product owner actually asks about an MCP server.
