get_stock_quoteLABSCO SUMMARY
Six lookups, no credentials — the fastest way to get market data into a conversation.
Nothing here needs an API key or a paid data plan, which makes it the low-friction option when you just want a price, a P/E or the analyst spread while thinking out loud. The name says trader, but the surface is read-only: there is no order, position or portfolio tool, and crypto support is limited to a handful of ticker formats.
What it is
An MCP tool built on the yfinance library and adapted for Claude Desktop. Six tools cover the everyday market lookups: a live quote with change and volume, a company overview with valuation and dividend metrics, daily open/high/low/close history, symbol search, the analyst recommendation spread, and insider transactions with position and share counts.
What you get
- A live quote: price, change, change percent, volume and timestamp —
get_stock_quote - Company profile and key metrics — sector, industry, market cap, P/E and forward P/E, dividend yield, 52-week high and low —
get_company_overview - Daily price history as open, high, low, close and volume per date —
get_time_series_daily - Symbol lookup returning ticker, name, instrument type and exchange —
search_symbol - The analyst recommendation spread by period: strong buy, buy, hold, sell, strong sell —
get_recommendations - Insider transactions with date, insider, position, transaction type, share count, value and ownership —
get_insider_transactions - Limited cryptocurrency coverage through ticker formats such as
BTC-USD,ETH-USDandDOGE-USD - Errors returned as a readable message rather than a crash — a bad symbol comes back as a failure explanation
Requirements
Nothing — no account, no key; the data comes through yfinance. Python 3.10 or higher and pip install -r requirements.txt from a clone, then point Claude Desktop at main.py with an absolute path. The project is yfinance-trader 0.1.0. If tools do not appear, the README's checklist is: confirm the server starts, use an absolute path in the config, make sure Python 3.10+ is on your PATH, and restart Claude Desktop.
Setup effort
Build from source — git clone https://github.com/SaintDoresh/YFinance-Trader-MCP-ClaudeDesktop
USE CASES
01
Checking a price and what moved it
Pull the live quote with change and volume, then read the company overview for the valuation context.
02
Looking at how a stock has traded recently
Fetch the daily series and reason over the open, high, low, close and volume without exporting a spreadsheet.
03
Seeing what the sell side thinks
Read the recommendation spread by period to see whether the balance has shifted rather than reading a single headline rating.
04
Checking insider activity before a decision
Pull recent insider transactions with position, share count and value to see whether people inside the company have been buying or selling.
