Dome Systems

Dome Systems is the enterprise agentic operations platform — the system of control for the agent era. Founded in 2024 by Dave McJannet (former HashiCorp CEO) and Marc Holmes, and backed by Redpoint Ventures, Bessemer Venture Partners, and Mango Capital, Dome registers every AI agent, governs every tool and model call against policy, and produces an immutable audit trail across the estate — regardless of runtime, cloud, or who built the agent. The Dome Platform is three control points — Registry (code), Gateway (tools), and Broker (models) — on a control plane of Cedar-based Authorization and Audit, administered through Go and Python SDKs, a REST API, a CLI, and a built-in MCP surface that exposes Dome itself to AI assistants.

Dome Systems is profiled on the APIs.io network. Tagged areas include Company, AI Agents, Agent Governance, AI Operations, and Authorization.

Dome Systems’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dome-systems: open an issue to ask a question, or submit a pull request to add artifacts.
