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 (46+)

Free (no auth):

tool	what it returns
track_record	the public verifiable record: graded picks, win rate, R-multiple ROI, calibration
leaderboard	every desk's machine-graded record, daily/weekly/monthly
instruments	discovery: all instruments, sports, categories + per-tool parameter docs
scan_sample	pick-of-the-day: a full-depth free sample of the sports engine
quote	cost preview for any tool + your remaining balance — never deducts

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_futures, scan_options, scan_event, scan_predmarket, scan_game, signal_sports, signal_polymarket, signal_racing, signal_golf, signal_equities, signal_weather, signal_screener, and more — call instruments for the full roster.

Every paid tool declares its cost in the description and machine-readably in _meta["signalpulse/cost"] (credits, credit type, USD range), and the free quote tool previews cost + balance first — an agent never discovers pricing by losing a credit. Spec-safe: notification-form tools/call 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.
