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 that this server's namespace belongs to myagents.click, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

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

Brazilian data lookup server: company records by CNPJ, postal codes, holidays, area codes, banks, tax codes, rates and CPF/CNPJ checks.

What you can do: Look up company information by CNPJ and validate CPF or CNPJ numbers
Resolve addresses and locations from CEP postal codes and DDD area codes
Retrieve Brazilian holidays and bank listings
Look up NCM product classification codes
Fetch financial indicators such as Selic, CDI and IPCA
When to use it: Useful when an assistant needs to verify or enrich Brazilian business and address data, check tax identifiers, or pull Brazilian reference data and interest or inflation indicators without building integrations for each source.
Requirements: Remote streamable HTTP endpoint; OAuth authentication is required. No environment variables or headers are declared.

Before you install

Requires an OAuth sign-in to the provider's endpoint, so account identity is shared with that third party. Lookups of company and CPF/CNPJ data are sent to the remote service; avoid submitting personal identifiers you are not authorized to process.

Installation

In SourceWeft

Open CNPJ e CEP in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
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/click.myagents%2Fbrazil-lookup/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.

Score

67% of the applicable checks met

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.
