Scout

For GTM engineers and RevOps teams running instrumented back-end stacks, Scout APM sits in a useful middle ground — it's an observability utility that can feed performance signals into broader workflow automation pipelines without requiring a full enterprise APM contract. The MCP server support is the real differentiator here: Scout has native agentic readiness, meaning you can wire it directly into an AI agent orchestration layer and have performance data callable on demand rather than waiting for a human to open a dashboard. Pricing starts free but the custom enterprise tier means procurement will likely get involved at scale — budget tier 4 is accurate once you're past the transactional limits on the mid-tier plans. The honest limitation is that log management and error monitoring only cover Ruby and Python today, so if your stack is PHP or Elixir, you're getting half the product until Scout expands language support.
