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
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
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 needing to write to upstream databases (read-only)
  • Users requiring direct access to closed datasets (e.g., COSMIC is not directly integrated)
  • Users expecting all advanced features without API keys
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 internet access to query public biomedical APIs
  • Optional API keys (NCBI, Semantic Scholar, OpenFDA, etc.) to improve rate limits or unlock features
  • Local read/write access for skills, cache, and local study data (e.g., `~/.local/share/biomcp`)
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
  • Upstream API rate limits may affect performance
  • Some data sources (e.g., KEGG) have licensing terms that restrict non-academic use
  • Features requiring API keys (e.g., OncoKB) may be incomplete without them
  • Local binary installations need regular updates for compatibility
