Overview

Description from the maker (original English)

Brazilian company, risk & public-tender data (CNPJ, CEIS/CNEP, PNCP) as x402-paid agent tools

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: EVM_PRIVATE_KEY, SOLANA_PRIVATE_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: EVM_PRIVATE_KEY, SOLANA_PRIVATE_KEY, SOLANA_RPC_URL, BRDATA_BASE_URL, X402_NETWORK

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "brdata": {
      "command": "npx",
      "args": [
        "-y",

        "EVM_PRIVATE_KEY": "your-value",
        "SOLANA_PRIVATE_KEY": "your-value",

        "BRDATA_BASE_URL": "your-value",
        "X402_NETWORK": "your-value"
      }
    }
  }

Run this in your terminal

claude mcp add brdata --env EVM_PRIVATE_KEY=your-value --env SOLANA_PRIVATE_KEY=your-value --env SOLANA_RPC_URL=your-value --env BRDATA_BASE_URL=your-value --env X402_NETWORK=your-value -- npx -y brdata-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "brdata": {
      "command": "npx",
      "args": [

        "X402_NETWORK": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "brdata": {
      "type": "stdio",
      "command": "npx",
      "args": [

      }
    }
  }
}

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • EVM_PRIVATE_KEY secret env
    0x private key of a DEDICATED wallet holding USDC on Base (pays per call). Paid tools return 402 without it; the free validate_cnpj tool still works.
  • SOLANA_PRIVATE_KEY secret env
    base58 or JSON-array secret key of a DEDICATED Solana wallet holding USDC (pays per call). Configure this and/or EVM_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises.
  • SOLANA_RPC_URL env
    Optional Solana RPC override used to build the payment (e.g. a Helius URL).
  • BRDATA_BASE_URL env
    Base URL of a brdata Worker. Defaults to the hosted production API (https://brdata.thomenz.me).
  • X402_NETWORK env
    'base' (mainnet, default) or 'base-sepolia' (testnet).

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Brdata MCP 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.

What keys or codes does it need?

You need to fill in: EVM_PRIVATE_KEY, SOLANA_PRIVATE_KEY

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?

The GitHub repo last changed –, and the latest version (0.3.7) reached the registry 3 months ago.

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.

What can I use instead?

brdata-mcp

An MCP (Model Context Protocol) server for Brazilian company & public-procurement data, for agent harnesses (Claude Code, Claude Desktop, …). It covers: CNPJ company registry lookup (basic + full due-diligence), company search/discovery across ~28M active companies by filters (CNAE activity, state/city, size, MEI, name), public tenders / licitações via PNCP (decode Compras.gov.br IDs, resolve, header, line items, edital documents, keyword search), NF-e & boleto decoding, CEP lookup, and batch document validation — for KYB, due diligence, and B2G (public-sector) sales intelligence.

Paid tools automatically settle the underlying x402-protected HTTP endpoints in USDC on Base or Solana using a wallet you configure; a call is charged only on success. Configure a Base wallet (EVM_PRIVATE_KEY), a Solana wallet (SOLANA_PRIVATE_KEY), or both — the x402 layer settles on whichever rail the server's 402 challenge advertises.

search_companies requires the Worker to have the Phase 2 database configured (Hyperdrive); otherwise it returns a 503 (and no payment is charged). MEI contact data is redacted (LGPD).

EVM_PRIVATE_KEYfor paid tools (Base)—0x-prefixed key of the paying Base wallet (holds USDC)

SOLANA_RPC_URLnopublic RPCOptional Solana RPC override used to build the payment (e.g. a Helius URL)
X402_NETWORKnobasebase (mainnet, matches the default URL) or base-sepolia (testnet → Solana devnet)

⚠️ Security

EVM_PRIVATE_KEY controls real funds. Anything that can read this process' environment (or the MCP config file) can spend from that wallet.

  • Use a dedicated wallet with a small balance, funded only with what you're willing to auto-spend. Never a personal or treasury key.
  • On testnet (base-sepolia) use test USDC only.
  • The key is read from the environment; it is never sent anywhere except to sign x402 payment authorizations for BRDATA_BASE_URL.

Use with Claude Code / Claude Desktop

Add to your mcpServers configuration:

{

"mcpServers": { "brdata": { "command": "npx", "args": ["-y", "brdata-mcp"], "env": { "EVM_PRIVATE_KEY": "0x " } } } }

For local development against wrangler dev, point BRDATA_BASE_URL at http://localhost:8787 and use X402_NETWORK=base-sepolia with a testnet wallet.

If you run from source instead of npm, use:

{

"mcpServers": { "brdata": { "command": "node", "args": ["/absolute/path/to/packages/brdata-mcp/dist/index.js"], "env": { "BRDATA_BASE_URL": "http://localhost:8787", "EVM_PRIVATE_KEY": "0x...", "X402_NETWORK": "base-sepolia" } } } }

Example

"Use brdata to run full due diligence on CNPJ 00.000.000/0001-91."

The agent calls lookup_company_full, which pays $0.03 in USDC and returns the consolidated English profile with partners and sanction checks.
