Best for
  • Developers who need programmatic access to A-share market and financial data
  • Users doing A-share Q&A or research/analysis through an AI assistant
  • Individuals wanting free A-share data access without a paid data account
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
Not for
  • High-frequency trading scenarios needing real-time tick-level or order-book data
  • Users needing Hong Kong, US, or other non-A-share market data
  • Institutional production environments with strict requirements on data accuracy/timeliness (data source is the free, unofficial Baostock service)
  • 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
  • Runs a local Python process launched via uv
  • Outbound network access to fetch market and financial data from Baostock
  • No API keys or account credentials required
  • 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
  • Data comes from the free third-party source Baostock, not officially guaranteed, with update delays (e.g. daily K-line data isn't stored until after 17:30)
  • The project was primarily developed and tested on Windows; cross-platform (macOS/Linux) compatibility is not thoroughly verified
  • No authentication mechanism — any client with access to the MCP server can call all tools and query all data
  • If Baostock's underlying interface changes, some tools may break without official support
  • 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
