Best for
  • Digital agencies operating AI agents and needing durable operational state
  • Accounting and bookkeeping firms requiring client-isolated knowledge and audit history
  • Consultancies needing structured artifact storage and approvals
  • Ecommerce companies running AI back-office operations
  • Software companies needing multi-agent workflow coordination
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
Not for
  • People looking for a chatbot or prompt wrapper
  • Users needing fully serverless deployment without persistent WebSocket connections
  • Teams seeking an open-source (non-Fair Source) license
  • Users looking for a lightweight task management tool rather than an operations platform
  • 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 access to a PostgreSQL database for state storage
  • Requires ability to maintain persistent WebSocket connections
  • May require local filesystem or external storage backend (e.g., Bunny CDN) for artifacts
  • Requires secrets in environment variables (e.g., NEXTAUTH_SECRET, EMPEROR_CLAW_MASTER_KEY)
  • 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
  • Self-hosting: risk of data loss if not properly configured; regular backups needed
  • Not open source (Fair Source) — restriction on offering it as a competing commercial product/service
  • Requires Node.js 20+ and PostgreSQL 16 as prerequisites
  • Not compatible with serverless platforms; requires a long-running process like a VPS or dedicated server
  • 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
