MCP SERVER

MCP Banco Inter

Banco Inter business banking from an assistant — balance, statements, and the full boleto lifecycle including issue, cancel and PDF download.

LABSCO SUMMARY

The whole boleto lifecycle, not just the balance.

Read-only banking integrations are common; this one issues and cancels collections, which is where the real time goes in a Brazilian back office. That also makes the sandbox flag the first thing to set — rehearse the issue-and-cancel path there before pointing it at a live account. mTLS with a certificate file is the setup cost, and it is the bank's requirement, not this server's.

What it is

An MCP server for the Banco Inter Empresas API. It covers two areas of the bank: the account side, meaning balance and statements, and the collections side, meaning boletos — issuing them, listing them by period and status, cancelling them, summarising them and downloading their PDFs. Authentication is OAuth2 over mTLS with the client certificate the bank issues.

What you get

  • consultar_saldo — the account's available balance, no parameters
  • consultar_extrato — transactions over a period, taking dataInicial and dataFinal, with baixar_pdf_extrato producing the same statement as a saved PDF
  • emitir_boleto — issue a new boleto with seuNumero, valorNominal, dataVencimento and the payer details
  • listar_boletos — list issued collections over a period, filtered by situacao, and sumario_boletos for a quantitative summary of the same window
  • cancelar_boleto — cancel an existing collection by codigoSolicitacao with a stated motivo
  • baixar_pdf_boleto — generate and save the PDF of one boleto

Requirements

Banco Inter developer credentials: CLIENT_ID, CLIENT_SECRET, a digital certificate and private key referenced by CERT_PATH and KEY_PATH, and the account number in X_CONTA_CORRENTE. INTER_IS_SANDBOX switches between the sandbox and production. Node.js 18 or higher, or Docker; the package is mcp-banco-inter (1.0.3 in package.json and server.json) and the local client entry runs npx -y mcp-banco-inter over stdio. MCP_TRANSPORT=streamable-http with MCP_HOST and MCP_PORT serves it at http://localhost:3000/mcp instead, which is how the Docker image runs by default. Generated PDFs land under STORAGE_PATH. The OAuth2 token is held in memory only and refreshed automatically.

Setup effort

One command plus credentials — npx -y mcp-banco-inter, then supply credentials
