@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:

• OAuth2 client_credentials — the server calls the token endpoint, caches the bearer until ~60s before expiry, and attaches Authorization: Bearer <token> to downstream calls.
• 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.
