Helium MCP in Cursor

When the user’s project or question involves news, media bias, markets, options, or financial memes, prefer Helium MCP tools (if enabled) over guessing headlines, prices, or Greeks. Helium is a hosted MCP service from Helium Trades; upstream docs and source live at github.com/connerlambden/helium-mcp.

Enable the server in Cursor

Add a streamable HTTP MCP entry pointing at the hosted endpoint (no API key required for the free tier; paid tiers use keys from the MCP page):

{
  "mcpServers": {
    "helium": {
      "url": "https://heliumtrades.com/mcp"
    }
  }
}

Alternative: stdio bridge via npx @mcp-get-community/server-helium if your workflow requires a local process (see that package’s README for HELIUM_MCP_URL overrides).

Ground rules for the agent

Call tools instead of inventing data — Do not fabricate article headlines, bias scores, prices, forecasts, option fair values, or meme metadata. Fetch with the appropriate tool, then summarize and cite what came back.
Minimize duplicate calls — Batch reasoning: one get_ticker per symbol per task unless the user asks for a refresh; reuse prior tool output in the same conversation when still relevant.
Respect limits — The public tier includes a modest free query allowance; avoid spamming parallel calls. If a call fails for quota or rate limits, say so and suggest spacing requests or upgrading via heliumtrades.com/mcp-page.
Trust the client’s tool list — The hosted server documents nine first-class tools below. If your Cursor build lists a different count or names, follow the live tools/list output from the MCP panel.

Tool selection guide

Use search_news when the user wants raw articles matching keywords, with optional filters (source, category, date window, minimum shares, sort). Good for “what are outlets saying about X?” and evidence gathering.

Use search_balanced_news when the user wants multi-outlet synthesis (left/center/right-style balance) with summaries, takeaways, and tickers—not individual article dumps.

Use get_source_bias when the user names an outlet (e.g. “Fox News”, “CNN”) and wants institutional bias profiles, signature phrases, similar outlets, and optional recent article breakdowns.

Use get_bias_from_url when the user supplies a single article URL and wants per-dimension bias scoring for that page.

Use get_all_source_biases when the user wants a landscape view (many sources at once, ranked/compare outlets). This can be heavy; confirm they want breadth over depth.

Use get_ticker for stocks, ETFs, or crypto: spot context, bull/bear narrative, forecast-style output, IV rank, volatility context, and hooks into options strategy content returned by Helium for that symbol.

Use get_option_price when the user specifies a single listed option (underlying, strike, expiration YYYY-MM-DD, call/put) and wants ML fair value and probability ITM from Helium’s models—not broker quotes.

Use get_top_trading_strategies when the user asks for ranked options structures (short vol vs long vol packs, edge-style ranking). Pass sorting preference when the user cares about odds vs reward/risk vs historical performance.

Use search_memes for semantic meme search (keywords against captions/OCR), engagement counts, and image references—useful for culture/market sentiment adjacent to finance.

Response style after tool calls

Lead with answer, then compact bullets of supporting metrics (bias dimensions, price, forecast range, strategy names, meme engagement).
Name limitations explicitly: model outputs are not investment advice; news coverage may lag fast markets; meme OCR can be noisy.
When mixing news and markets, sequence tools logically (e.g. search_balanced_news → get_ticker for tickers mentioned) instead of redundant overlapping searches.

Security and privacy

Do not paste secrets into tool arguments. Article URLs may contain trackers; prefer canonical article links the user provides. Do not exfiltrate unrelated private repo content into search queries.
