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.

How Vinkius works: one connection, every tool, in any AI
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.

Who it's for

Built for the work Celcoin Open Finance API owners hand off.

  • 02

FAQ

Questions Celcoin Open Finance API owners ask.

  • 01

    How does the MCP handle authentication?

    The MCP uses OAuth2 client credentials to mint a bearer token. It manages the 40-minute token lifetime and automatically refreshes it if a request fails.

  • 02

    Can I use this in a production environment?

    The MCP defaults to the Celcoin sandbox. Production use requires an mTLS certificate and a source-IP allowlist, which is intended for self-hosted or edge callers.

  • 03

    Does this move real money?

    Yes, the pix_payment and ted_transfer capabilities initiate actual financial movements. Always confirm the amount, recipient, and client code before authorizing the agent.

  • 04

    How do I check if a Pix payment was successful?

    You can use the pix_payment_status capability by providing the transaction ID, client code, or end-to-end ID returned during initiation.

  • 05

    What is the difference between Pix and TED in this MCP?

    Pix is used for immediate or dated transfers via keys or accounts, while TED is used for interbank same-day transfers requiring a BACEN finality code.

  • 06

    Where do I get the Celcoin Client ID and Secret?

    The Celcoin integration team issues them during your homologation. For testing, the Celcoin docs publish a public sandbox test pair for the bill payment, recharge or transfer products. point the base URL at the sandbox and use that pair right away.

  • 07

    Sandbox or production. which base URL do I set?

    Leave the base URL empty (or set the sandbox URL) to call the sandbox, which needs no extra setup. Per Celcoin's docs, the production base URL additionally requires an mTLS certificate issued by Celcoin plus a source-IP allowlist. a hosted runner cannot provide either, so production is intended for self-hosted or edge callers that hold the certificate.

  • 08

    Do pix_payment and ted_transfer actually move money?

    Yes. both initiate real BRL transfers in the connected environment (in the sandbox, against sandbox balances). The capabilities tell the agent to confirm the amount, parties and purpose with you before calling. Track each one afterwards with pix_payment_status or ted_transfer_status.

  • 09

    What is client_finality in a TED?

    It is the BACEN finality code describing the purpose of the interbank transfer. a 6-digit code such as 010101. "99999" means no specific finality (other), in which case the free-text description becomes required and is what the receiver sees on their statement.
