How to Give Claude Desktop, Claude Code & Cursor Live Stock Quotes, Technicals & Options Greeks in 60 Seconds (MCP Server)

#mcp #claude #cursor #python

Large Language Models like Claude and Cursor are exceptional at reasoning over financial relationships, writing backtesting code, and summarizing market catalysts - until they have to guess a current stock price, P/E multiple, RSI-14 reading, or option contract Delta from stale training data or noisy web search snippets.

Using the Model Context Protocol (MCP), you can connect ApexTick's 8-Tool Streamable HTTP MCP Server (com.apextick/mcp) directly to Claude Desktop, Claude Code, Cursor, or OpenCode in a single JSON block - zero local Docker containers or Python wrappers required.

What the 8 Read-Only Compound MCP Tools Provide

Instead of forcing the AI agent to chain 15 separate REST requests (burning context tokens and latency), com.apextick/mcp (scored 100/100 on MCPTRY and 5/5 TDQS on Glama) exposes 8 compound, read-only tools:

  1. get_quote (Free Hobbyist+) - Spot price, session change %, 52-week range, and volume across 66,400+ global equities, ETFs, FX pairs (EURUSD=X), and crypto (BTC-USD).
  2. search_tickers (Free Hobbyist+) - Resolve company names or ticker prefixes across global exchanges.
  3. get_watchlist_brief (Free Hobbyist+) - Batched Markdown comparison table for up to 20 tickers in a single call plus market breadth.
  4. get_price_history (Free Hobbyist+) - Historical OHLCV bars (1m to 1mo) plus dividend ex-dates, stock splits, and quarterly EPS surprises.
  5. analyze_ticker (Trader Pro+) - Valuation multiples (P/E, P/B, P/S, TTM Revenue, EPS, ROE, Dividend Yield) and 52-week positioning.
  6. explain_price_move (Trader Pro+) - Technical indicator snapshot (RSI-14, SMA-20/50/200, MACD, ATR-14, 30d Volatility) + earnings catalyst attribution.
  7. get_options_chain (Trader Pro+) - Live near-the-money option chains plus historical daily option contract OHLCV, IV & Black-Scholes Greeks (Delta, Gamma, Theta, Vega, Rho) for active and expired contracts.
  8. screen_market (Quant+) - Market-wide gainers, losers, volume leaders (filterable by GICS sector and market cap), and high-IV option underlyings.
