The governed runtime door

Run the whole agent platform through one clear boundary.

Graph OS is the process you run. It authenticates MCP, REST, A2A, browser, terminal, desktop, and messaging requests; composes the agent and graph services behind them; and supervises the connector fleet from one serving lifecycle.

What GraphOS owns

GraphOS owns Process lifecycle, MCP and REST composition, unary A2A, request policy, fleet supervision, and optional WebUI hosting.

GraphOS delegates Agent decisions to agent-utilities, durable state and reasoning to epistemic-graph, source effects to connector services, and presentation to Agent WebUI.

GraphOS does not copy those authorities. It binds their public contracts into one identity-aware application surface and reports unavailable authority explicitly.

Follow one request

1. Enter through one door An MCP, REST, A2A, or WebUI request reaches the GraphOS serving process.
2. Establish authority GraphOS verifies identity, tenant, requested action, and the applicable policy.
3. Route to the owner Agent work reaches agent-utilities; graph work reaches epistemic-graph; source work reaches an admitted connector.
4. Return evidence The caller receives a transport-specific response backed by the same governed result and provenance.
