Helium
Helium is a combined MCP server and REST API from Helium Trades pairing an in-house news-and-bias engine (3.2M+ articles across 5,000+ sources, each scored across 15+ bias dimensions) with live market data — ticker quotes, AI-generated bull/bear cases, and options pricing with full Greeks — plus a semantic meme search. Ten REST endpoints (`/mcp_search/`, `/mcp_ticker/`, `/mcp_option_price/`, etc.) all return JSON and are mirrored as MCP tools at a single streamable-HTTP endpoint for drop-in use in Claude Desktop, Cursor, or Windsurf. Live requests against `/mcp_search/` and `/mcp_ticker/` confirmed working keyless access (first 50 queries per IP subnet are free, tracked without sign-up) and an open `Access-Control-Allow-Origin: *` header; beyond the free tier it bills $0.02/query via Stripe with no monthly minimum, so it's metered rather than freemium.
