Elastic

Monitoring

SIEM and observability platform for agent tool call logging and anomaly detection.

What it solves

MCP gateways and servers generate tool-call logs, but those logs only help if they land somewhere searchable with alerting attached. Elastic gives you the SIEM and observability backend to centralize MCP audit logs, search them during investigations, and alert on anomalies.

How it works

Tool-call logs from your MCP gateway or instrumented servers are shipped to Elasticsearch. Detection rules and dashboards flag patterns like new servers appearing, unusual argument values, or spikes in failures, and the same data supports forensic queries later.

Pros & cons

Pros

Mature SIEM with detection rules, dashboards, and long-term retention.
Scales from a single self-hosted cluster to a managed cloud service.
Many teams already run it, so MCP logs join an existing security data lake.

Considerations

Not MCP-aware out of the box — you build the ingest pipeline and detection rules yourself.
Operating Elasticsearch well takes real expertise if you self-host.
Cost grows with log volume, which agent workloads can inflate quickly.

When to choose it

Choose Elastic when you already run it (or another SIEM you can swap in) and need MCP audit data inside your existing detection and forensics workflow.
