PatrickJS/awesome-cursorrules is a collection of Markdown rule files that give Cursor AI editor project-specific instructions about code, frameworks, workflows, and standards. Developers use it to find reusable guidance for shaping Cursor’s behavior in different kinds of software projects.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01022 | $0.01022 |
| Opus 5 | $0.00511 | $0.00511 |
| Sonnet 5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
helium-mcp-cursorrules-prompt-file scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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_tickerper 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/listoutput 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.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

helium-mcp-cursorrules-prompt-file is a cursor rule published in the GitHub repository PatrickJS/awesome-cursorrules (40,734 stars, last pushed 3mo ago), licensed CC0-1.0. It adds 1,022 tokens to every session, about $0.0051 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
