Server Variants

[chughtapan]

Server variants allow MCP servers to expose multiple parallel configurations (e.g., claude-optimized, compact, coding-assistant) that clients can intelligently select based on their context. Each variant includes a unique identifier, human-readable description, and key-value hints.

The primary motivation is cross-agent tool reusability — enabling the same MCP tools to serve fundamentally different agent architectures or models with optimized surface areas tailored to each use case.
