Overview

Description from the maker (original English)

MCP server for Sicoob — Pix (cob/cobv/DICT), Cobrança (boleto), SPB (OAuth2 + mTLS)

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: SICOOB_CLIENT_ID, SICOOB_CLIENT_SECRET, SICOOB_CERT_PATH, SICOOB_KEY_PATH

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: SICOOB_CLIENT_ID, SICOOB_CLIENT_SECRET, SICOOB_CERT_PATH, SICOOB_KEY_PATH, SICOOB_ENV

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "sicoob": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sicoob"
      ],
      "env": {
        "SICOOB_CLIENT_ID": "your-value",
        "SICOOB_CLIENT_SECRET": "your-value",
        "SICOOB_CERT_PATH": "your-value",
        "SICOOB_KEY_PATH": "your-value",
        "SICOOB_ENV": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add sicoob --env SICOOB_CLIENT_ID=your-value --env SICOOB_CLIENT_SECRET=your-value --env SICOOB_CERT_PATH=your-value --env SICOOB_KEY_PATH=your-value --env SICOOB_ENV=your-value -- npx -y @codespar/mcp-sicoob

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "sicoob": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sicoob"
      ],
      "env": {
        "SICOOB_CLIENT_ID": "your-value",
        "SICOOB_CLIENT_SECRET": "your-value",
        "SICOOB_CERT_PATH": "your-value",
        "SICOOB_KEY_PATH": "your-value",
        "SICOOB_ENV": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "sicoob": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sicoob"
      ],
      "env": {
        "SICOOB_CLIENT_ID": "your-value",
        "SICOOB_CLIENT_SECRET": "your-value",
        "SICOOB_CERT_PATH": "your-value",
        "SICOOB_KEY_PATH": "your-value",
        "SICOOB_ENV": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • SICOOB_CLIENT_ID required env
    Sicoob OAuth client_id issued via the Developers Portal after cooperative onboarding.
  • SICOOB_CLIENT_SECRET secret required env
    Sicoob OAuth client_secret.
  • SICOOB_CERT_PATH required env
    Absolute path to the mTLS client certificate (.crt or .pem). BACEN mandates mTLS for Pix v2.
  • SICOOB_KEY_PATH secret required env
    Absolute path to the mTLS private key (.key or .pem).
  • SICOOB_ENV env
    Environment: 'sandbox' or 'production'. Defaults to 'sandbox'.

Common questions

Is MCP Sicoob 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: SICOOB_CLIENT_ID, SICOOB_CLIENT_SECRET, SICOOB_CERT_PATH, SICOOB_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 (0.1.0-alpha.4) 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-sicoob

MCP server for Sicoob — Brazil's largest cooperative bank network.

Sicoob is consistently a top-4 PSP by Pix volume in Brazil. The Sistema de Cooperativas de Crédito do Brasil aggregates hundreds of regional cooperatives behind a single Developers Portal exposing Pix, Cobrança (boleto), and SPB APIs.

Status: alpha (0.1.0-alpha.1)

Sicoob's Developers Portal is gated by cooperative onboarding. The endpoint paths in this server are best-guesses based on (a) BACEN Pix v2 standard paths, (b) Sicoob's public documentation snippets, 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 cooperative member can validate.

Install

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

Environment

SICOOB_CLIENT_ID="..."       # OAuth client_id from Sicoob's Developers Portal

SICOOB_CLIENT_SECRET="..." # OAuth client_secret SICOOB_CERT_PATH="/abs/path/to/client.crt" # mTLS client certificate SICOOB_KEY_PATH="/abs/path/to/client.key" # mTLS private key SICOOB_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 to downstream calls.
  2. mTLS — BACEN mandates mutual TLS for Pix v2, and Sicoob 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.

The cert + key bundle is issued by Sicoob's Developers Portal after cooperative onboarding and is distinct from the OAuth credentials.

Run

# stdio (default)

npx @codespar/mcp-sicoob

HTTP transport

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

Caveats

  • Paths are unverified. See the TODO(verify) markers in src/index.ts. Onboarded cooperatives should validate against their portal-issued OpenAPI spec and open a PR.
  • Sandbox host is a guess. Sicoob issues a sandbox subdomain per cooperative; override by editing BASE_URL if your provisioned sandbox URL differs.
