Trading Signals MCP

An MCP server that gives Claude, Cursor, LangChain and any other MCP-capable agent one-line access to the Trading Signals Toolkit: a $0.10 GO / CAUTION / NO_GO pre-trade check, a futures event-risk gate, session brief and macro event study built from US government macro data (BLS, Federal Reserve, Treasury, CFTC), SEC Form 4 insider buys and cluster buys, Base token safety verdicts, and small quant calculators. Each tool call pays for itself automatically over x402 in USDC on Base, from a wallet you control, with a per-call spend cap. You can also try the HTTP API with a free API key (100 calls/month, no card) from the pricing page.

Failed calls (bad input, upstream outage) return an error and are not charged.

Setup

You need Node.js 18.17+ and a dedicated Base wallet private key holding a few dollars of USDC on Base mainnet (no ETH needed; the facilitator pays gas).

Env var	Required	Default	Meaning
X402_PRIVATE_KEY	yes (to call tools)	–	0x-prefixed private key of the paying wallet
MAX_USD_PER_CALL	no	0.50	Hard cap per call; anything pricier is refused before signing
TRADING_SIGNALS_BASE_URL	no	https://signals.incomefather.com	API base URL

Run it directly:

X402_PRIVATE_KEY=0xYOUR_DEDICATED_WALLET_KEY npx -y x402-trading-signals-mcp

How payment works

Each tool calls one HTTPS route. The API answers 402 Payment Required with the exact USDC amount; this server signs an EIP-3009 transferWithAuthorization for that amount (only USDC on Base mainnet, only up to MAX_USD_PER_CALL) and retries. Paid results include a _payment field with the settlement transaction and a BaseScan link. Without X402_PRIVATE_KEY the server still starts and lists its tools; calling one returns a clear "no wallet configured" error and charges nothing.

Security

• Use a dedicated, low-balance wallet. Create a fresh wallet just for this, fund it with only what you are willing to spend (for example $2–$5 of USDC on Base), and never use a key that holds other funds.
• The key stays on your machine: it is read from the environment, used only to sign payment authorizations locally, and never sent to the API or logged.
• Keep MAX_USD_PER_CALL low. The default ($0.50) allows every tool; set 0.05 to block the $0.10 bundle.
• Your MCP client config file now contains a private key: don't commit or share it.

Development

npm install
npm run build   # syntax/import check (plain ESM, no compile step)
npm test        # starts the server over stdio, lists tools, checks unpaid/capped errors (spends nothing)
