Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Brazilian company, risk & public-tender data (CNPJ, CEIS/CNEP, PNCP) as x402-paid agent tools
These three are never merged into one score: opinions, measurements and popularity are different things.

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.

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 (Base) | — | 0x-prefixed key of the paying Base wallet (holds USDC) |
SOLANA_PRIVATE_KEY | for paid tools (Solana) | — | base58 or JSON-array secret key of the paying Solana wallet (holds USDC). Configure this and/or EVM_PRIVATE_KEY |
SOLANA_RPC_URL | no | public RPC | Optional Solana RPC override used to build the payment (e.g. a Helius URL) |
X402_NETWORK | no | base | base (mainnet, matches the default URL) or base-sepolia (testnet → Solana devnet) |
EVM_PRIVATE_KEY controls real funds. Anything that can read this process' environment (or the MCP config file) can spend from that wallet.
base-sepolia) use test USDC only.BRDATA_BASE_URL.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" } } } }
"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.
