Best for
  • Individuals or teams who want to read/search/organize/send email directly from an MCP client
  • Users with multiple IMAP/SMTP accounts who want unified management
  • Users comfortable with uv/uvx and local credential setup who can configure their own mail accounts
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
Not for
  • Users unwilling to store email passwords/credentials locally
  • Setups requiring OAuth (e.g., modern Gmail/Outlook auth) rather than username/password login, which the source material does not confirm is supported
  • Users wanting a fully cloud-hosted email service with no local configuration
  • 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
  • Stores and uses email account credentials (username/password) in local keyring or managed SQLite storage
  • Reads and searches mailbox content via IMAP
  • Sends email on the user's behalf via SMTP
  • Local filesystem access to read/write configuration (TOML file or SQLite database)
  • 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
  • Email credentials are stored locally (legacy TOML/keyring, or managed SQLite in V2); exposure of this storage could allow unauthorized mailbox access
  • Granting an AI client the ability to send email creates risk of unintended or malicious sends via prompt misuse
  • Migrating from legacy configuration to V2 involves credential import, which can hit conflicts or missing-credential issues if done incorrectly
  • 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
