The unusual part is the billing: instead of registering for API keys at Yahoo, FRED, EDGAR and CoinGecko separately, each call pays for itself from a wallet. That removes the onboarding entirely and replaces it with a different decision — you are putting a private key with a live USDC balance into your client's environment, so keep the balance small.
A local stdio server that proxies five financial data calls to a hosted backend and signs the payment for each one itself. Data comes from Yahoo Finance, FRED, SEC EDGAR and CoinGecko. There is no account to create: billing runs on x402 micropayments from a wallet you control.

`pip install findata-mcp` (or `uvx findata-mcp`), version 0.3.5, launched as the `findata-mcp` command. Set `EVM_PRIVATE_KEY` to a wallet key holding USDC on Base mainnet — each call signs a $0.01 transfer, so roughly $1 covers 100 calls. A free trial gives 50 calls/day before that. `FINDATA_BACKEND_URL` points the client at a self-hosted backend instead.
One command plus a key — pip install findata-mcp, then supply credentials
