01 — FROM EXPERTISE TO APPLICATION

One model.
More than a calculation.

Pack your financial knowledge into something people and agents can actually use. Start with a question. Build the app that answers it.

YOUR KNOWLEDGE

The cash flow model

Inputs, formulas, domain rules and the financial question you want to solve.

model = knowledge + logic

A mini application

Inputs, scenarios and reports for people.

A Web API

A calculation service for your systems.

An AI MCP connection

Financial tools your agents can call.

THE MICROSERVICE IDEA

One model packages the calculation, UI and optional case storage into one application, with versioned releases.

Build your first model

03 — BUILT FOR AGENTS, FROM THE GROUND UP

Let your agents work.
Keep the reasoning.

Give AI agents a financial engine they can call through MCP. Run calculations autonomously, or bring a person into the loop when the workflow needs a decision.

  • Structured inputs and calculation results
  • Saved cases with inputs, versions and results
  • Traceable calculations you can inspect later
Connect your AI workflow

06 — EXCHANGE KNOWLEDGE. EXCHANGE VALUE.

Give a little.
Calculate a lot.

Accounts have silver and golden credits. Both pay for operations; silver is spent first. New accounts receive 1,000 silver credits. While billing is offline, you can get a free silver refill when your balance reaches zero. Only golden credits have an estimated monetary value; payments and payouts are offline.

A FEW THINGS WORTH KNOWING

Good questions.
Clear answers.

What does one cash flow model include?

A DecCF model defines financial inputs, rules and calculations. It can be published as a mini application with a UI, a versioned Web API and an AI MCP connection. Case storage can be enabled for saved inputs and results.

Can an AI agent run calculations and save results?

Yes. With the MCP integration configured, agents can discover financial tools, calculate scenarios and save cases when storage is enabled. Account operations require authentication and permissions. Your workflow can run autonomously or include a human review.

Do I need a credit card or a subscription?

No credit card is needed to create an account, and there is no monthly subscription. New accounts receive 1,000 silver credits. Silver and golden credits both pay for services; silver is spent first. While billing is offline, a free silver refill is available when your balance reaches zero. Only golden credits may qualify for a future payout; payments and payouts are currently offline.

How do I integrate a model into an existing process?

Use its published Web API from your BPM or business system, with the model's OpenAPI documentation. Use MCP for agent workflows, or the mini application's interface for a person. Select the version and permissions your process needs.
