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
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
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 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
  • 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 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
  • 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
  • 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
