Common questions

Is MCP Stone 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.

You need to fill in: STONE_CLIENT_SECRET

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?

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.

Authentication

Stone uses OAuth2 client credentials for authentication. The server automatically manages token refresh.

Sandbox / Testing

Stone provides a sandbox via the developer portal.

Get your credentials

Go to Stone Open Bank Documentation
Register as a developer
Create an application to get OAuth2 credentials
Set the environment variables

Environment Variables

Variable	Required	Description
`STONE_CLIENT_ID`	Yes	OAuth2 client ID
`STONE_CLIENT_SECRET`	Yes	OAuth2 client secret
`STONE_BASE_URL`	No	Override base URL (default `https://api.openbank.stone.com.br/api/v1`; sandbox `https://sandbox-api.openbank.stone.com.br/api/v1`)
`STONE_AUTH_URL`	No	Override the OAuth2 token URL (default `https://accounts.openbank.stone.com.br/auth/realms/stone_bank/protocol/openid-connect/token`; sandbox `https://sandbox-accounts.openbank.stone.com.br/auth/realms/stone_bank/protocol/openid-connect/token`). Up to 0.2.2 the token call went to `login.openbank.stone.com.br`, which does not exist, so every tool failed at authentication.

create_recipient — Marketplace / split recipients
create_transfer_batch — Batch transfer processing
get_boleto — Fetch boleto details
