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.

One connector, every AI

Railz works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Railz to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Railz, so you can see the experience inside your AI.

It does not authenticate your account with Railz. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Railz owners ask.

  • 01

    What kind of financial data can my agent access?

    Your agent can access normalized data from accounting, banking, and commerce platforms, including balance sheets, P&L statements, and bank transactions.

  • 02

    Which AI clients can I use with this MCP?

    You can use this MCP with any compatible client, such as Claude, Cursor, Windsurf, or VS Code.

  • 03

    Do I need to manually export data from QuickBooks or Xero?

    No. The Railz MCP pulls the data directly from those connections so your agent can read it instantly.

  • 04

    Can I manage multiple businesses through one agent?

    Yes. You can list all registered businesses in your Railz account and switch between them to pull specific reports or audit data.

  • 05

    How do I set up the credentials?

    Once you subscribe on Vinkius, you will need to enter your Railz Client ID and Client Secret to authorize the connection.

  • 06

    Can I access data from multiple accounting platforms like QuickBooks and Xero simultaneously?

    Yes! Railz normalizes data across all supported providers. Use the list_businesses and list_connections capabilities to identify the target entity, then query reports which will return in a consistent format regardless of the underlying source.

  • 07

    How do I retrieve a Balance Sheet for a specific company connection?

    First, find the relevant connection_id for the business using list_connections. Then, use the get_balance_sheet capability with that ID to fetch the snapshot of assets and liabilities.

  • 08

    Does this integration allow creating new invoices or only reading them?

    The current toolset focuses on read-only operations for auditing and analysis, such as list_invoices, list_bills, and list_accounts. This ensures safe exploration of financial data without accidental modifications.
