Dataroma

A high-performance Model Context Protocol (MCP) server for extracting superinvestor portfolios and financial intelligence from Dataroma.com. This server is compatible with any MCP-enabled AI client, including Claude Desktop, Cursor, Cline, and ZeroClaw.

Features

• One-Shot Homepage Scraper: Extracts all 10+ market lists and the manager directory in a single request for maximum efficiency.
• Aggressive 24h Caching: Uses an in-memory cache with disk persistence (dataroma_cache.json) to provide instant responses and avoid rate limits.
• Enriched Portfolio Data: 13F holdings automatically include recent insider transaction (Form 4) summaries.
• Full Market Intelligence: Direct access to Big Bets, 52-Week Lows, Most Owned Stocks, and Real-time Activity.

Available Tools

• get_investor_holdings(manager_id): Get full 13F holdings for a specific manager (e.g., 'BRK' for Buffett).
• get_realtime_insider_trades(symbol): Get the 10 most recent insider transactions for a stock ticker.
• get_market_intelligence(list_type): Access Latest Insider Buys, Most Owned, Big Bets, Q1/Q2 Buying Trends, High Conviction Lows, and Insider Concentration.
• list_superinvestors(): Full directory of all 80+ tracked superinvestors and their IDs.
• invalidate_cache(key): Manually clear specific keys or the entire cache to force a fresh scrape.

Installation

The recommended way to run this server is using uvx (which acts like npx for Python). This allows you to run it directly from PyPI without manually installing dependencies or cloning the repository.

uvx dataroma-mcp
