Best for
  • Individual users needing shared persistent memory across multiple AI tools.
  • Developers who want to self-host a memory layer on Cloudflare's free tier.
  • Users prioritizing data privacy and control, as data stays in their own cloud account.
  • Users wanting a quick setup with complete ecosystem support (desktop app, CLI, extensions, etc.).
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
Not for
  • Teams needing collaborative memory (currently single-user design).
  • Users wanting zero technical setup without touching Cloudflare (except desktop app).
  • Users requiring offline or local-only memory (depends on cloud services).
  • Strict compliance environments that require non-cloud infrastructure.
  • 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 Cloudflare account to deploy the Worker and infrastructure.
  • Requires an AUTH_TOKEN (or password) to authorize all clients.
  • Supports OAuth 2.0 dynamic client registration; clients do not need to embed the token in configs.
  • For calendar, email, and Notion integrations, requires iCal links, app passwords, or Notion connection secrets.
  • 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 means you are responsible for maintenance and updates.
  • Data is stored on Cloudflare, subject to Cloudflare's privacy policy (though within your own account).
  • Free tier may have usage limits (e.g., vector index size).
  • If you forget your password, you must log into Cloudflare to reset; you might temporarily lose access to memories.
  • Deploying with incorrect parameters (e.g., Vectorize dimensions) can degrade search functionality.
  • 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
