1.0 Capabilities

Ask, analyze, reconcile.
With the account's data, not estimates.

The agent picks the right tool for each question, walks the whole period page by page, and answers with the numbers that back the answer. From today's balance to tracing a Pix (Brazil's instant payment), without exporting a spreadsheet.

  • FIG 1.1

    Balances and statement

    Your cash position in one question

    The real-time available balance of every account and the consolidated statement for the period, with inflows, outflows and running balance. For cash flow, daily position and reports for any period.

    Payments and incoming payments

    Any Pix, traced end to end

    Look up a transaction by external_id, by its Pix end-to-end ID or by platform_id and see every stage, with who paid or got paid. Or list everything sent to a CPF or CNPJ (company tax ID), and everything received from it.

    Corporate cards

    The card invoice, explained

    The entity's prepaid Mastercard cards, purchases in the period, the open invoice with what is still pending confirmation, and the invoice history. The invoice CSV comes as a temporary link.

    Reconciliation

    Check the period, line by line

    Attach the spreadsheet from your system and ask for a check: the agent walks the account statement for the period and flags what didn't match, by each entry's external_id.

2.0 Governance

Delegate the analysis,
not the approval.

The agent checks, compares and explains. The decision stays with your team: payments keep going through your account's approval rules at Trio.

Frequently asked
questions

What is Trio MCP?

It's Trio's MCP server. MCP (Model Context Protocol) is the open standard AI agents use to connect to other systems. With Trio MCP, Claude and other MCP-compatible clients read your organization's banking data: balances, statements, outgoing and incoming payments, transfers, corporate cards and their invoices.

Can the agent make payments?

No. Trio MCP tools read data. Payments are still created and approved at Trio, through your account's approval rules.

What data can the agent see?

Only your organization's. Every call runs as the credentials that authenticated the session and is limited to that organization's data. Card numbers always arrive masked.

Which agents work with Trio MCP?

Claude and other MCP-compatible clients. The agent learns each tool from its description, which explains when to use it and which one to prefer for a similar question.

How do amounts and dates reach the agent?

Amounts always in cents (R$50,000.00 arrives as 5000000), dates and times in ISO 8601, and listings paginated, with before and after cursors in the metadata section. That way the agent walks the whole period before answering.

How do I get started?
