Axiom
Observability built for agents and humans
What is Axiom
Axiom collects, stores, and analyzes event and telemetry data — logs, metrics, traces, and events — in a single platform, with real-time ingestion and querying at petabyte scale. It's built for GTM engineers and founders running early-stage to growth-stage products who need full observability without standing up multiple tools. The standout capability is tracing agent workflows and tracking cost and latency across AI providers, which makes it genuinely useful for teams shipping LLM-based products. Virtual fields let you transform data at query time rather than re-ingesting it, which keeps pipelines lean. That said, Axiom is an engineering-layer tool — it won't replace a dedicated BI or analytics product if your stakeholders need polished dashboards outside the dev workflow.

Vanderbuild take
For GTM engineers and founders who are shipping AI-native products and need a single place to watch logs, traces, and agent behavior, Axiom is one of the few observability tools that was actually designed with that use case in mind rather than retrofitted for it. The MCP server support is the real agentic wedge here — you can call Axiom directly from an AI agent or orchestration layer, making it a natural fit as an observability backbone in automated pipelines. Free or near-free to start, with usage-based pricing at $0.03/GB of storage, so the risk to test is low. The honest limitation is that Axiom is an engineering tool first — if your team needs business-facing dashboards or non-technical stakeholders need to self-serve on the data, you'll want to layer something else on top.
Agentic stack profile
MCP serverYesLive MCP server — agents can call this tool directly.
Axiom MCP Server is a Model Context Protocol server implementation that enables AI agents to query data using Axiom Processing Language (APL) and manage dashboards and monitors. It supports various MCP tools for data and dashboard management.
Open MCP →APIRESTProgrammatic access available.
REST API — straightforward to call from any agent or workflow tool. Rate limits and auth vary by plan.
API docs →Agentic readinessNativeBuilt for agents from the ground up.
MCP server + agent-friendly API + at least one autonomous workflow out of the box. The bar for 'Native' is high — only a handful of tools currently qualify.
