How is security handled for transactions?

Authentication is handled via ECDSA public and private cryptography. The MCP manages the signing process internally using the private key you provide.

What kind of transfers can I make?

You can execute both Pix and TED transfers to pay vendors, employees, or other entities.

Can I manage corporate cards through the AI?

Yes, you can use the MCP to create new enterprise corporate credit cards on the fly.

How do I see my account balance?

You can ask your agent to check your atomic balance or total cash on hand using the balance capability.

Does this work with any AI client?

It works with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

How do I securely pass the Stark Bank ECDSA Private Key to MCP?

Inside Stark Bank, when you generate your API project, the website will generate a Public/Private Keypair or ask you to provide one. You must grab the Private Key (often starting with -----BEGIN EC PRIVATE KEY-----) and paste that entire raw multiline text into the STARK_PRIVATE_KEY input inside the MCP client perfectly as it is.

Can the bot process Corporate Card requests automatically?

Yes! If you instruct the agent to orchestrate the generation using the capability stark_create_corporate_card, the API instantly spins up a valid, active Corporate Virtual Card attached to your Master Balance in real-time.

How does the Stark Bank transfer function differ from basic gateway Pix?

Stark Transfer allows hyper granular outbounds. Instead of just pushing a basic Pix key, the stark_create_transfer can route massive payrolls, TED systems tracking BankCode, ISPB nodes and branch validation—giving you raw underlying banking protocol access.

Will Stark API throttle the connection if the Agent lists too many historic Boletos?

StarkBank allows huge enterprise-grade API ceilings per second. Pulling hundreds of statements using stark_list_boletos naturally respects rate limits easily while functioning inside LLM chat turns.

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.
