Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account ElToro1855 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Public knowledge server that gives an assistant 55 curated categories on Brazilian foreign exchange, IOF tax, US accounts, stablecoins and international…

What you can do: Search a semantic index across all 55 knowledge categories and get the most relevant excerpts for a question.
Read individual category resources on IOF, US bank accounts, international transfers, stablecoins, dollar cards, freelancer income, B2B payments, foreign property, education abroad, income tax, compliance and competitor comparisons.
Use prompt templates for exchange-rate consultations, comparisons with competitors and savings simulations.
When to use it: Useful when answering questions about sending or receiving money across borders in Brazil: avoiding IOF, opening a US account, receiving dollars as a freelancer, stablecoins, declaring foreign accounts, or comparing providers. It is a reference content source, not a transaction tool.
Requirements: The README points to a hosted streamable-HTTP endpoint, so no local runtime or credentials are needed for that setup; the manifest instead lists an npm package run locally over stdio. No authentication, API keys or environment variables are declared. Network access is required for the hosted endpoint.

Before you install

The content is published by a commercial exchange provider and includes comparisons and simulations that favour its own service, so treat it as marketing-influenced reference rather than neutral advice. No authentication is declared, so do not send personal or financial data. The manifest and README disagree on transport and hosting, so confirm which setup you are installing.

Installation

In SourceWeft

Open Ozav Mcp Server in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
