Common questions

Is MCP Santander safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SANTANDER_CLIENT_ID, SANTANDER_CLIENT_SECRET, SANTANDER_CERT_PATH, SANTANDER_KEY_PATH

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0-alpha.3) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@codespar/mcp-santander

MCP server for Santander Brasil — 3rd largest private bank in Brazil.

Completes the top-3 BR private-bank trio: Itaú + Bradesco + Santander. Same OAuth2 + mTLS shape as its peers; different merchant contract.

Merchants with meaningful Pix, boleto, and cash-management volume integrate directly with Santander instead of going through a PSP.

Status: alpha (`0.1.0-alpha.1`)

Santander's Developer Portal is contract-gated — the full OpenAPI specs for Pix, Cobrança, Arrecadação, and Extrato are only visible to onboarded merchants. The following pieces are verified against Santander's public integration guides:

Production host: https://trust-open.api.santander.com.br
Sandbox host: https://trust-sandbox.api.santander.com.br
OAuth2 token: /auth/oauth/v2/token
Cobrança v2 base: /collection_bill_management/v2/workspaces/{workspace_id}/bank_slips

Remaining paths (Pix, Arrecadação, Extrato) are best-guesses based on (a) BACEN Pix v2 standard paths, (b) Santander public marketing, and (c) conventions shared across Itaú / 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.

Install

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

Environment

SANTANDER_CLIENT_ID="..."       # OAuth client_id from Santander's Developer Portal

SANTANDER_CLIENT_SECRET="..." # OAuth client_secret SANTANDER_CERT_PATH="/abs/path/to/client.crt" # mTLS client certificate SANTANDER_KEY_PATH="/abs/path/to/client.key" # mTLS private key SANTANDER_ENV="sandbox" # or "production" (default: sandbox)

Authentication

Two factors are both required on every call:

OAuth2 `client_credentials` — the server POSTs to /auth/oauth/v2/token on the trust-open (or trust-sandbox) gateway, caches the bearer until ~60s before expiry, and attaches Authorization: Bearer to downstream calls.
mTLS — BACEN mandates mutual TLS for Pix v2, and Santander's trust-open gateway 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 Santander Developer Portal after your merchant contract is signed. They are distinct from the OAuth credentials.

Cobrança: workspace model

Santander's Cobrança v2 is workspace-scoped. Before registering boletos you provision one or more workspace_ids via the Developer Portal — each binds a convênio, boleto/Pix billing mode, and webhook URL. The create_boleto, get_boleto, and cancel_boleto tools all take a workspace_id argument.

Run

# stdio (default)

npx @codespar/mcp-santander

HTTP transport

MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-santander

Caveats

Pix / Arrecadação / Extrato 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.
Cobrança cancel is modelled as a PATCH with status: "BAIXADO"; the covenant-specific cancellation semantics may differ.
Arrecadação barcode validation is server-side in this alpha — no client-side mod-10 / mod-11 check yet.
