Overview

AI-generated overview

A remote MCP server giving assistants a registry of Brazilian financial institutions, sourced regulatory signals, and cited Q&A.

What you can do
Look up Brazilian financial institutions in an entity registry, including sourced regulatory signals attached to them, and get answers to questions with citations. The manifest lists no individual tools, so the exact operations are not documented here.
When to use it
Useful when an assistant needs to identify Brazilian financial institutions or check regulatory signals about them, and answers must be backed by cited sources.
Requirements
A remote endpoint at onssa.org reached over streamable HTTP, with OAuth authentication required. No environment variables or headers are declared.
Before you install
Access requires OAuth sign-in, so the server receives account credentials through that flow. The manifest lists no tools, so what it can read or change is not documented; verify before relying on it.

Installation

In SourceWeft

  1. Open Onça — Brazil financial competitive & regulatory intelligence in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.marcioyoshida%2Fonca/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
