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 | $0.00000 | $0.00686 |
| Opus 5 | $0.00000 | $0.00343 |
| Sonnet 5 | $0.00000 | $0.00137 |
| Haiku 4.5 | $0.00000 | $0.00069 |
Grade A, and why
mcp_finnhub 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 12d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Critical: Reuse Prior Results
Follow-up questions ("what's the market cap?", "what do analysts say?") should use data from earlier tool responses before making new calls. If you already fetched a company profile or financials, surface that data directly.
Tool Selection

|---|---|
| Latest news headlines | get_market_news(category) |
| Current stock price | get_stock_quote(symbol) |
| Company background | get_company_profile(symbol) |

Stock Symbols
Use uppercase US ticker symbols: AAPL, MSFT, GOOGL, TSLA.
For non-US stocks, use the exchange-suffixed format the user provides.
News Categories
get_market_news accepts: general, forex, crypto, merger.
Default is general. Match the category to the user's intent. If results seem sparse or irrelevant, try a different category. Use min_id from the last article to paginate for more results.
Multi-Step Workflows
"Should I invest in X?" or "Tell me about X stock":
get_company_profile(symbol)for company contextget_stock_quote(symbol)for current priceget_basic_financials(symbol)for valuation metricsget_recommendation_trends(symbol)for analyst consensusget_insider_transactions(symbol)for insider buying/selling activity
"What's happening in the market?":

"What are insiders doing at X?":

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mcp_finnhub is a skill published in the GitHub repository NimbleBrainInc/mcp-finnhub (1 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 686 tokens. 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 2026-08-31.

mcp_webfetch
The prompt is sent to an LLM along with the page's markdown. Specific prompts get better results.
mcp_ipinfo
Follow-up questions ("this IP", "that one", "is it a VPN?") → reuse IP from prior result.
mcp_granola
All tools that accept meeting identifiers use meetingid (not docid, id, or documentid). The meetingid value comes from the id field in search results and meeting lists.
sector-rotation
An analysis framework for comparing industries in the Chinese A-share stock market, using business conditions, price momentum, valuation, and money flows. It produces rankings and higher- or lower-allocation suggestions.
strategy-pivot-designer
Detect backtest iteration stagnation and generate structurally different strategy pivot proposals when parameter tuning reaches a local optimum.
twitter-reader
Read Twitter/X for financial research using opencli (read-only). Use this skill whenever the user wants to read their Twitter feed, search for financial tweets, view bookmarks, look up user profiles, or gather market sentiment from Twitter/X.
