Details
From the project READMEgov-transparency-mcp
Watch the watchers. Congressional stock trades, federal contract awards, campaign finance, lobbying filings, and new regulations — nine MCP tools over official US government data, paid per call with x402 USDC on Base. No account, no API key, no subscription.
Commercial trackers sell congressional-trading data behind monthly subscriptions. Here it is per-call, in structured JSON, for agents: $0.005–$0.02 a query.

Data sources
All official, all public domain: US House Clerk financial disclosures (parsed from the source PTR PDFs), USAspending.gov, the Federal Election Commission, the Senate Lobbying Disclosure Act database, the Federal Register, and Congress.gov. Trade disclosures lag transactions by up to 45 days — that is the law's reporting window, not a data delay. Current trade coverage: US House (Senate planned); paper-filed disclosures are indexed with PDF links but not parsed into rows.
Setup
{
"mcpServers": {
"gov-transparency": {
"command": "npx",
"args": ["-y", "@forgemeshlabs/gov-transparency-mcp"],
"env": {
"WALLET_PRIVATE_KEY": "0x..."
}
}
}
}
WALLET_PRIVATE_KEY must be a dedicated low-balance wallet holding a small amount of USDC on Base mainnet — never your primary wallet. get_endpoint_spec works without one.
Requirements
Node.js 20+ and a dedicated, low-balance Base wallet funded with USDC. The server refuses to sign for any payee other than the two Utility Grid wallets, any network other than Base mainnet, any asset other than USDC, or any amount over the cap ($0.02 per call, $10 per session). The env vars X402_MAX_PRICE_USD and X402_SESSION_BUDGET_USD can only lower those caps. Requests are same-origin, time out after 60 seconds, are capped at 2 MB, and never follow redirects.
How payment works
Each call makes a normal HTTP request; the server answers 402 Payment Required with exact terms, the client signs a USDC transfer authorization (EIP-3009) and retries, and the settlement transaction hash comes back in the response under _payment. Atomic: no data without payment, no payment without data.
License
MIT — code only. The underlying government data is public domain.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
