Best for
  • Users who need Yahoo Finance data in AI conversations
  • Analysts and developers researching stocks, funds, and ETFs
  • MCP client users who need structured financial data and charts
  • Hevy PRO users who want AI assistants to directly access their workout data
  • People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
  • Anyone needing summaries and insights from their training data
  • Scenarios needing clean, structured web context fed to an AI assistant
  • Users already on the Firecrawl platform who want to call its scraping capability directly via MCP
Not for
  • Production financial systems requiring guaranteed real-time, complete, or stable data
  • Users treating market data as investment advice or a trading decision by itself
  • Users requiring authentication, data sources, or client integrations not documented in the source
  • Users without a Hevy PRO subscription (API key required)
  • Users who want to use the server without an API key
  • Those needing delete workflows (Hevy API does not expose delete endpoints)
  • Simple static-page scraping where you don't want to depend on a third-party API and incur call costs
  • Sites that explicitly disallow automated access (robots.txt)
Required permissions
  • A network connection to access Yahoo Finance data
  • The source does not document a user login or API key requirement
  • Docker requires a locally available Docker runtime when using the Docker method
  • Requires HEVY_API_KEY environment variable for Hevy API authentication
  • Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
  • Read operations can fetch workouts, routines, folders, templates, history, and user info
  • Requires a Firecrawl API key to call; cost and quota are governed by the Firecrawl account
  • firecrawl_agent/firecrawl_interact perform automated browser interaction, which may trigger login or form-submission flows on the target site
Risks and side effects
  • Yahoo Finance fields and availability may vary by symbol, fund, data version, and coverage
  • Analyst, holder, and fund datasets may be incomplete or partially unavailable
  • Screener results are subject to Yahoo Finance query limits, commonly up to 250 rows per request
  • Financial data and charts should not be treated as investment advice
  • API key can be misused if leaked; do not expose in URLs, logs, or screenshots
  • Create operations may produce duplicates on retry; update operations replace existing records
  • The server sends data to the Hevy API and may send telemetry to external services unless disabled
  • Bulk crawl/map tools can generate significant request volume against a target site — respect the site's rate limits and terms of service
  • firecrawl_agent's interactive action chain is longer — define task boundaries clearly before running it to avoid accidentally triggering actions on a sensitive site
