@codespar/mcp-itau

MCP server for Itaú Unibanco — Brazil's largest private bank.

Itaú operates the largest private-bank API surface in the country. Merchants running high-volume Pix, boleto, and cash-management workloads integrate directly instead of going through a PSP.

Status: alpha (0.1.0-alpha.1)

Itaú's Developer Portal is contract-gated — the full OpenAPI specs for Pix, Cobrança, Arrecadação, and Extrato are only visible to onboarded merchants. The endpoint paths in this server are best-guesses based on (a) BACEN Pix v2 standard paths, (b) Itaú's public marketing pages, and (c) conventions shared across Santander / Bradesco / BB. Every unverified path is flagged TODO(verify) in the source.

Pin to exact versions during 0.1.x; paths will be corrected to match the portal spec once an onboarded merchant can validate.

Tools (22)

Install

npm install @codespar/mcp-itau@0.1.0-alpha.1

Environment

ITAU_CLIENT_ID="..."       # OAuth client_id from Itaú's Developer Portal
ITAU_CLIENT_SECRET="..."   # OAuth client_secret
ITAU_CERT_PATH="/abs/path/to/client.crt"   # mTLS client certificate
ITAU_KEY_PATH="/abs/path/to/client.key"    # mTLS private key
ITAU_ENV="sandbox"                          # or "production" (default: sandbox)

Authentication

Two factors are both required on every call:

1. OAuth2 client_credentials — the server calls the token endpoint, caches the bearer until ~60s before expiry, and attaches Authorization: Bearer <token> to downstream calls.
2. mTLS — BACEN mandates mutual TLS for Pix v2, and Itaú enforces it across product families. The server loads the client certificate and private key from the paths you set, builds a Node https.Agent, and routes every request through it.

You obtain the cert + key bundle from the Itaú Developer Portal after your merchant contract is signed. They are distinct from the OAuth credentials.

Run

# stdio (default)
npx @codespar/mcp-itau

# HTTP transport
MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-itau

Caveats

• Paths are unverified. See the TODO(verify) markers in src/index.ts. Onboarded merchants should validate against their portal-issued OpenAPI spec and open a PR.
• Sandbox host is a guess. Itaú issues a sandbox subdomain per merchant; override by editing BASE_URL if your provisioned sandbox URL differs.
• Arrecadação barcode validation is server-side in this alpha — no client-side mod-10 / mod-11 check yet.
