Email Provider Abstraction Layer

A Node.js application for managing email workflows using the ModelContextProtocol (MCP).

Unique: Decouples MCP tool definitions from email provider implementations via a pluggable interface, allowing new providers to be added without modifying tool schemas or agent code

vs others: More maintainable than hardcoding provider logic in tools because changes to one provider don't affect others, vs. monolithic implementations that require tool refactoring per provider

Unique: Implements a provider adapter pattern at the MCP server level, translating provider-specific APIs into unified MCP schemas — clients never see provider differences, and new providers can be added by implementing a single adapter interface without changing MCP definitions

vs others: Unlike email libraries that expose provider-specific APIs to the client, this abstraction ensures LLM prompts and tool definitions remain provider-agnostic, reducing hallucination risk when switching providers and enabling true multi-provider agent support
