Direct answer
What is SiriusCore?
SiriusCore is a headless, AI-native enterprise application and operational workbench built on a finance and ERP foundation. Its business operations are designed exclusively for AI agents, with no built-in human operational UI. Its only native human interface is an administration console for permissions, audit and oversight.
Through native CLI, MCP and REST, agents discover business context, perform valid operations and verify the resulting state. SiriusCore can execute core work itself or coordinate the enterprise systems already in place.
Our design principle
The final bottleneck is the application.
When AI takes responsibility for completing a task, it needs an application it can understand and operate directly. Software organized around human screens and manual steps makes the agent work around the application. SiriusCore gives it a native place to work.
For enterprise task completion,
Application > Runtime > Harness
- Make the business operable
- The application supplies business meaning, valid actions, authoritative state and enforced controls. It defines what work can actually be completed.
- Give AI a place to build and run
- The runtime provides compute, storage and execution for the programs and capabilities an agent needs to carry out the task.
- Coordinate the agent
- The harness organizes models, tools, context and execution. Its work becomes simpler when the application already speaks the agent’s language.
What changes
Give AI responsibility for the work. Keep authority with people.
Spend reasoning on the business
Self-describing context and native operations let agents focus on business decisions and execution. Navigating human screens no longer has to be part of the job.
Start with a compatible agent
Supported business work can run without a separate knowledge or memory tool or a tailor-made harness. The application supplies its own business model, operational state and rules.
Keep control in human hands
Set identities, permissions and approval boundaries in the administration console. The application enforces those controls and records what happens while agents carry out the work.
Let AI adapt the application
Authorized agents can configure, extend, test and release business functions. When people need a screen, AI can build an interface around the task.
Bring existing systems along
Coordinate enabled ERP, CRM, planning and custom systems through one agent-facing application. Adopt an AI-native way of working process by process.
Native to the operator
Let AI work in its own language.
Computer use is a compromise with software designed for people. Reading screens, navigating menus and reproducing clicks spends agent effort on the interface. SiriusCore lets agents work directly with business objects, valid operations and results.
| What the task needs | When AI follows a human workflow | SiriusCore’s native approach |
|---|---|---|
| Understand the business | Interpret screens, field labels and instructions written for people. | Discover self-describing schemas, relationships, records and available operations. |
| Perform the work | Reproduce the navigation and interaction steps of a human operator. | Invoke business operations through CLI, MCP or REST, with application logic and permissions enforced. |
| Continue and verify | Reconstruct progress from screens and previous interactions. | Read durable task and workflow state, handle exceptions and check the resulting business records. |
| Adapt to the task | Work within the sequence and screens of an existing human workflow. | Configure and extend functions under control, then test and use them. Add a human interface when needed. |
Headless by design
Human interfaces, when the work calls for them.
SiriusCore’s only native human UI is its administration console. When people need operational screens, AI can build them on SiriusCore or in an agent runtime such as FleeceTide.
The foundation
AI-native operations
Business objects, actions, workflow and controls remain in the application. CLI, MCP and REST are native ways to operate it.
CLI · MCP · REST
Built in
Administration for people
Manage identities and permissions, review audit logs, configure controls and oversee execution. People retain authority over what agents may do.
Built by AI when needed
Operational interfaces for people
Ask AI for a form, dashboard or workspace suited to the task. The interface uses SiriusCore’s business operations and remains subject to its permissions and controls.
Explore FleeceTide’s runtime →Traditional applications add CLI or MCP so agents can participate. SiriusCore starts with AI-native operations and adds a human UI where it helps. The interface becomes an extension of the application, rather than the architecture that defines it.

Your existing systems
One coherent application for AI. Clear roles for every system.
SiriusCore gives agents a consistent business model while coordinating the systems behind it. Each process defines where data is authoritative and where operations run.
Execute natively
SiriusCore owns the business objects, workflow and controls for the chosen scope and performs the work directly.
Write through
SiriusCore validates and controls an operation, then writes to the external system that remains authoritative.
Coordinate systems
Maintain task state and dependencies while coordinating operations, results and exceptions across applications.
Bring context together
Read or synchronize external data into a consistent model while keeping its source system authoritative.
Adoption paths
Start with the work you want AI to own.
Connect the existing landscape
Introduce one agent-facing application across current ERP, CRM, planning and custom systems.
Run one process natively
Choose order-to-cash, reconciliation or another defined process. Run it in SiriusCore and integrate the adjacent systems.
Expand the foundation
Move selected finance and ERP scope into SiriusCore as you redesign more work around AI agents.
Implementation follows the same philosophy: agents configure, extend and validate the capabilities they will use. Your team and FDE partners provide objectives, access, guidance and review. ConstaVitality provides product enablement.
Independent by design
A native environment for agentic AI.
A compatible agent can perform supported enterprise work directly in SiriusCore without an external knowledge or memory tool or a tailor-made harness. The business model, current state, valid operations and controls are already in the application.
It is the environment AI should feel at home in: the work is expressed in a language it can discover, understand and act on. Add the other products when your objectives call for more.

FAQ
Questions buyers ask about SiriusCore.
How is SiriusCore different from a traditional ERP with AI added?
SiriusCore designs business operations exclusively for AI agents. Native CLI, MCP and REST expose self-describing business context, valid operations, workflow state and application-enforced controls. It has no built-in human operational UI. People govern the application through its administration console, and AI can build additional human interfaces when needed.
Why use a headless application instead of AI computer use?
Computer use makes an agent interpret screens and reproduce interactions designed for people. SiriusCore gives it direct, structured access to the business model, current state, permitted operations and results. Our design priority is to let AI spend its reasoning on completing the business task in an environment built for it.
Does SiriusCore have a user interface for people?
Its only native human interface is the administration console, covering configuration, identities, permissions, approvals, audit logs and oversight. Day-to-day business operations are designed for AI agents. Human operational screens can be added as extensions.
Can AI build a human operational UI on SiriusCore?
Yes. AI can build task-specific forms, dashboards and workspaces on SiriusCore, or build and run them in an agent runtime such as FleeceTide. These interfaces use SiriusCore’s business operations and remain subject to its permissions and controls. The AI-native application stays the foundation; the human interface is an optional extension.
Do we need a separate memory tool or a custom harness?
No. A compatible agent can perform supported enterprise work directly in SiriusCore without a separate knowledge or memory product or a tailor-made harness. SiriusCore supplies self-describing context, operational state, business actions and controls. TeemLush adds specialist knowledge and shared team memory; FleeceTide adds a centralized, governed harness and runtime. Both are optional additions.
Does SiriusCore replace our ERP?
SiriusCore can provide an AI-native application above existing systems, run a selected process natively, or progressively take on finance and ERP scope. Its role is chosen process by process, so adoption can begin with one business objective.
Which system remains the system of record?
That responsibility is defined for each process and data domain. SiriusCore may execute natively, write through to another authoritative system, coordinate several systems, or synchronize external context. The implementation makes those responsibilities explicit.
How do people stay in control when AI does the work?
People set identities, roles, data access and approval requirements through the administration console and review execution through audit logs. SiriusCore enforces permitted operations, row- and column-level access, task boundaries and safe-write behavior inside the application. Agents carry out work within those boundaries.
Can agents configure and extend SiriusCore themselves?
Yes, when authorized. Self-describing schemas, metadata-driven configuration and separated sandbox, test and production environments let agents understand, implement, validate and release business functions. People define the objectives, permissions and release decisions; agents build and use the capabilities they need.
Is SiriusCore an enterprise ontology?
SiriusCore includes an executable enterprise model of business objects, relationships, states, actions and rules. That model is part of a working application: it connects native finance and ERP operations, durable workflow, permissions, audit and coordinated execution across systems.
How is SiriusCore deployed?
Private cloud is the default; on-premise deployment is available by arrangement. Business scope, connected systems, controls and current capability are confirmed for each process and deployment. ConstaVitality provides product enablement for users and partners; FDE and solution-provider partners deliver customer implementation services.
