How do I install ScalpStream Data?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does ScalpStream Data need an API key?

The publisher lists these environment variables: EVM_BASE_PRIVATE_KEY, SCALPMCP_MAX_PRICE_USD, SCALPMCP_BUDGET_USD, SCALPSTREAM_STATUS_TOKEN.

What transport does ScalpStream Data use?

ScalpStream Data runs locally over stdio.

When was ScalpStream Data last checked?

Last checked 2026-11-11. Pay-per-call recalls, border waits, fuel, air quality, wash-sale checks via x402; your engine too.

Credentials from the publisher

EVM_BASE_PRIVATE_KEY — Base-mainnet private key holding a little USDC, used to pay per call. Leave unset to run in preview-only mode, where every paid tool returns the free preview and the exact price instead. Gas is sponsored by the facilitator, so the wallet needs USDC and no ETH. Use a throwaway key.
SCALPMCP_MAX_PRICE_USD — Refuse any single call quoted above this many dollars. Defaults to 0.10. Checked before anything is signed, so a refusal costs nothing.
SCALPMCP_BUDGET_USD — Refuse once this process has spent this many dollars in total. Defaults to 2.00.
SCALPSTREAM_STATUS_TOKEN — For ScalpStream managed-trading subscribers only: the status token from the enrolment page (st-...), read by my_engine_status. It reads that one engine's status and can do nothing else. Leave unset otherwise.

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.

ScalpStream MCP server

An MCP server that buys small, factual datasets at call time with your own wallet, over x402 — roughly $0.01 a call, no account, no subscription, no API key anywhere in the flow.

Most MCP servers wrap an API you already hold a key for. This one pays as it goes. The seller holds no keys either: settlement runs through a facilitator that sponsors gas, so the only key in the system is yours, held in memory for the lifetime of the process and never written anywhere.

It is useful before you fund anything. With no key configured, every paid tool returns the free preview and the exact quoted price, so you can see what you would be buying before deciding to buy it.

Tools

Tool	What you get
`options_research`	Ranked short-term US equity options candidates with the observed metrics behind each ranking. Impersonal research data — no trade plan, sizing, or verdict.
`municipal_income`	Federally tax-exempt municipal bond funds and muni CEFs, with tax-equivalent yields for the 24/32/37% brackets.
`crypto_research`	Ranked cryptocurrency candidates: technical signals plus a Fear & Greed and news-sentiment overlay.
`crypto_yields`	Where to earn interest on crypto: DeFi staking APY, stablecoin lending, liquidity-pool yields across CeFi and DeFi, risk-adjusted by TVL.
`cheapest_fuel`	Cheapest fuel by location and grade. Station-level for Spain, France, Italy; official regional averages for the US.
`air_quality`	Current AQI and pollutants anywhere in the world, an EPA-based verdict on exercising outdoors, and the cleanest window ahead.
`border_crossings`	US ports of entry ranked by all-in time — drive plus current CBP wait — per lane type. The nearest crossing is often not the fastest.
`product_recalls`	Active US recalls for a product, brand, ingredient or vehicle across FDA, NHTSA and CPSC in one query, with severity normalised onto one scale, the hazard, the remedy, and the lot numbers that tell whether a specific unit is affected.
`payment_status`	What's configured, what's been spent. Makes no network call and costs nothing.

Install

go install github.com/DV1-321/scalpstream-mcp/cmd/scalpmcp@latest

Configure

Claude Desktop (claude_desktop_config.json), Claude Code, or any MCP client:

{
  "mcpServers": {
    "scalpstream": {
      "command": "scalpmcp",
      "env": {
        "EVM_BASE_PRIVATE_KEY": "0x...",
        "SCALPMCP_MAX_PRICE_USD": "0.10",
        "SCALPMCP_BUDGET_USD": "2.00"
      }
    }
  }
}

Omit env entirely to run in preview-only mode.

Variable	Default	Meaning
`EVM_BASE_PRIVATE_KEY`	(unset)	Base-mainnet key holding a little USDC. Unset = preview-only.
`SCALPMCP_MAX_PRICE_USD`	`0.10`	Refuse any single call quoted above this.
`SCALPMCP_BUDGET_USD`	`2.00`	Refuse once the process has spent this much in total.

Spending safety

Real money moves, so the design refuses rather than overspends:

Both limits are checked before anything is signed. A refusal costs nothing and never reaches the network.
An unset limit means the default, never "unlimited." A missing config line must not become unbounded spending.
Spend is recorded only when the data is actually delivered. If a paid request then fails, the error says settlement state is unknown rather than implying nothing moved — you may need to reconcile against the chain.
Gas is sponsored by the facilitator, so the wallet needs USDC and no ETH.

Use a throwaway key funded with a dollar or two. Never one holding balances you care about.

Payment rails

Sellers accept USDC on Base, Arbitrum and Polygon, and XRP or RLUSD on the XRP Ledger. This client pays USDC on Base, preferring it over other EVM rails regardless of the order the server lists them in.

What the data is not

The financial tools return impersonal, general-circulation research data, identical for every buyer. They are not investment advice, not personalised, and carry no trade plan, position sizing, or buy/sell verdict. The operator trades securities that appear in these feeds. Every response carries its own disclaimer and source attribution; read them.
