Your AI Assistant Doesn't Know Today's Market News. Here's the Fix.
Your AI Assistant Doesn't Know Today's Market News. Here's the Fix.
Ask Claude or ChatGPT what's moving a stock today and you'll get one of three answers: a polite refusal, a confident guess from months ago, or a plausible-sounding summary that turns out to be wrong. None of them are useful when you're trying to make a decision before the market does.
The problem isn't the model. It's that the model can't see today. You can fix that in about two minutes by giving your AI assistant a live, structured feed of financial news through MCP — so instead of guessing, it queries a real news database and answers from sourced, current data.
The blind spot every LLM has
Every large language model has a knowledge cutoff — a date after which it simply doesn't know what happened. For most questions that's fine. For markets it's the whole game. "What did the Fed signal at this week's meeting?" or "Why is NVIDIA down today?" fall on the wrong side of that line, and the model either admits it or, worse, fills the gap with something that sounds right.
Even with built-in web browsing, you're not there yet. You get a handful of unranked links, no way to filter by ticker or sentiment or date, no company disambiguation, and no guarantee the sources are the ones you'd trust. It's better than nothing, but it isn't research you'd act on.
Why copy-pasting headlines isn't the answer
The manual workaround is to paste headlines into the chat yourself. It works once, badly. There's no sentiment scoring, no way to tell whether "Apple" means the ticker or the fruit, no date filtering, and the moment you send your next message the context is stale again. You've turned your analyst into a clipboard.
What you actually want is for the assistant to go get the news itself — filtered, structured, and current — every time you ask.
What changes when your assistant can pull live news
Connect finlight's MCP server and your assistant gains a new ability: it can query finlight's real-time news database directly, in the middle of a conversation. Every answer is sourced and current, not hallucinated — it comes from actual articles, each already scored for sentiment and tagged with the companies involved.
You ask in plain language. The assistant handles the filtering:
"Show me all negative-sentiment news about NVIDIA from the last 24 hours."
"Find news mentioning my watchlist — AAPL, MSFT, GOOGL, AMZN — sorted by most recent."
"Summarize today's coverage of the Federal Reserve meeting, grouped by topic."
"What's the sentiment distribution for Tesla news this quarter?"
Behind each of those, the assistant is searching by keyword, filtering by ticker, sentiment, source, country, and date range, pulling full article content, and resolving each company to its real identifiers — so a question about a dual-listed company returns the right stock, not a namesake on another exchange.
What you can do with it
- Morning briefings on demand. "Anything I need to know about my portfolio before the open?" — answered from this morning's news, not last quarter's training data.
- Sentiment at a glance. Ask for the tone of coverage on a name and get a distribution grounded in scored articles, with a confidence signal on each.
- Research without tab-switching. Analysts and PMs monitor tickers and themes inside the assistant they're already using, instead of juggling ten news tabs.
- Fast exploration before you build. Quant and dev teams poke at the data conversationally to see what's there before writing a line of integration code.
How it works, briefly
MCP (Model Context Protocol) is an open standard that lets AI assistants connect to external tools and
data. finlight runs an MCP server at https://mcp.finlight.me; you authorize it once with your API
key, and from then on Claude or ChatGPT can call it whenever a question needs live news. There's no
code to write and nothing to maintain.
Setup takes about two minutes — the step-by-step for Claude Desktop and ChatGPT is in finlight in Your AI Assistant: The MCP Server. If you'd rather compare MCP against REST, WebSocket, and webhooks first, see which delivery method fits which job.
Who it's for
- Analysts and portfolio managers who want current, sourced answers without leaving their assistant.
- Research teams synthesizing coverage across many sources in one question.
- Anyone using Claude or ChatGPT for market research who's tired of "I don't have information after my training cutoff."
Get started
- Get your API key — the free tier is enough to try this.
- Connect Claude or ChatGPT following the MCP setup guide.
- Ask it something only today's news can answer.
