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 using a wallet you configure; a call is charged only on success.

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).
Configuration
Environment variables:
| Var | Required | Default | Meaning |
|---|---|---|---|
BRDATA_BASE_URL | no | https://brdata.thomenz.me | Base URL of a brdata Worker (defaults to the hosted production API) |
EVM_PRIVATE_KEY | for paid tools | — | 0x-prefixed key of the paying wallet (holds USDC) |
X402_NETWORK | no | base | base (mainnet, matches the default URL) or base-sepolia (testnet) |
⚠️ 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<dedicated-wallet-key-with-USDC>"
}
}
}
}
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 $0.10 in USDC and returns the
consolidated English profile with partners and sanction checks.
