Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Insider trades, prediction-market odds, US macro and x402 data. Pays per call in USDC on Base.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
DF_WALLET_PRIVATE_KEY, DF_WALLET_MNEMONIC, DF_SESSION_BUDGET, DF_MAX_PRICE_PER_CALLValues marked secret are keys to your account. Never share them or paste them into a chat.

You need a dedicated wallet with a little USDC on Base (e.g. $2–5). No ETH is needed — x402 payments are gasless for the payer.
Settings → Developer → Edit Config, then add:
{
"mcpServers": { "df-market-intelligence": { "command": "npx", "args": ["-y", "df-market-intelligence-mcp"], "env": { "DF_WALLET_PRIVATE_KEY": "0xYOUR_DEDICATED_WALLET_KEY", "DF_SESSION_BUDGET": "1.00" } } } }
Same command: npx -y df-market-intelligence-mcp, with the environment variables below.
| Variable | Required | Default | Meaning |
|---|---|---|---|
DF_WALLET_PRIVATE_KEY | one of these two | – | Private key of the paying wallet (USDC on Base) |
DF_WALLET_MNEMONIC | one of these two | – | Or its 12/24-word recovery phrase (first account) |
DF_SESSION_BUDGET | no | 1.00 | Max USD this server may spend per session |
DF_MAX_PRICE_PER_CALL | no | 0.10 | Refuse any single call priced above this |
DF_API_URL | no | https://df-data-agent.vercel.app | API base URL |
Without a wallet, the free tools still work and paid tools explain how to set one up.
The same data is available directly over HTTP with any x402 client: see the catalog, OpenAPI spec and llms.txt.
