Best for
  • Traders and investors needing real-time market data
  • MCP client users who want to query options flow, dark pool, and congressional trades in natural language
  • Researchers interested in smart money flows and institutional holdings
  • 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
  • Users without a need for market data or unable to provide an API key
  • Users preferring traditional APIs over MCP integration for latency-sensitive applications
  • Users requiring free or anonymous access
  • 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
  • Requires a valid Unusual Whales API key (UW_API_KEY)
  • Access to public stock fundamentals and technical indicator endpoints
  • Local mode requires Node.js 20+ runtime
  • Remote mode requires network access to api.unusualwhales.com
  • 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
  • API key leakage could lead to unauthorized use or charges; keep it secure
  • Market data usage may be rate-limited (default 120 requests per minute)
  • Remote server availability and stability depend on the provider
  • Data accuracy is guaranteed by the provider; may have delays or errors
  • 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
