SignalPulse MCP Server

Hosted MCP server for market intelligence with a public, machine-graded track record — FX, crypto, futures, options, equities, sports, racing, and prediction markets.

• Endpoint: https://signalpulse.theaslangroupllc.com/api/mcp

• Transport: Streamable HTTP (stateless, POST JSON-RPC 2.0 — no session, no SSE required)

• Auth: none required for free tools. Paid tools take an X-API-KEY header (credit packs) or per-call x402 USDC micropayments on Base — fully agent-native, no signup needed.

Why this one

Most market MCP servers are free data plumbing. SignalPulse sells graded calls: every paid tool returns either the single highest-probability trade call for a market or a full analyst report — and the engine's history is public and machine-graded (R-multiple ROI, win rate, calibration buckets) via the free track_record tool, so an agent can verify performance before spending anything.

Tools (44)

Free (no auth):

Paid (1 credit or x402 per call): analysis (any natural-language market question → analyst report) plus scanners/signal desks: scan_forex, scan_market, scan_crypto, scan_crypto_lite, scan_futures, scan_event, scan_predmarket, scan_game, scan_racing, scan_golf, signal_sports, signal_polymarket, signal_racing, signal_equities, signal_stormy, signal_rainy, signal_screener, signal_tokenized, and more — call instruments for the full roster (or tools/list; the roster is generated from the live endpoint manifest, so it is always current).

Every paid tool declares its credit type in its description, and an uncredentialed call returns the structured 402 payment envelope with the exact USDC price before anything is charged — an agent never discovers pricing by losing a credit. Spec-safe: notification-form tools/call (no id) is never executed (no silent credit burn).

Connect

Claude Desktop / any streamable-HTTP client:

{
  "mcpServers": {
    "signalpulse": {
      "url": "https://signalpulse.theaslangroupllc.com/api/mcp",
      "headers": { "X-API-KEY": "sp_YOURKEY" }
    }
  }
}

Works without the header too: free tools respond, paid tools return a structured x402 402 payment envelope (pay USDC out-of-band at the resource URL, then retry, or buy a credit pack).

Pricing

Credits are sold in packs (Stripe or crypto): analysis $1.00–$1.49/credit, signals $1.70–$2.49/credit by pack size. x402 per-call prices ride the 402 envelope. Full details: llms.txt.
