How does this MCP help with splitting costs?

It uses the generate_contribution_plan capability to calculate exactly how much each person owes based on the total price.

Can I use this with Claude or Cursor?

Yes, you can connect this MCP to any MCP-compatible client like Claude, Cursor, or Windsurf via Vinkius.

Does it account for physical space?

Yes, the feasibility capability considers your available storage capacity when evaluating a purchase.

What happens after we decide to buy something?

The agent can use the formulate_action_plan capability to give you a list of logistical next steps.

How do we track who owns an item?

You can use the create_ownership_record capability to establish social or legal ownership status.

How does the system decide if a purchase is worth it?

The analyze_purchase_feasibility capability calculates a utility score by weighing the item's expected use against its storage and maintenance requirements, then compares it to your set decision threshold.

Can I split costs between different people?

Yes, you can use generate_contribution_plan to distribute the total cost among all contributors based on their individual limits and agreed-upon ownership rules.

How is ownership determined?

Ownership is established using create_ownership_record, which assigns equity and control rights based on the financial contributions made by each person.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 4 capabilities
