Custom Tool Registration And Handler Binding

via “tool registration and lifecycle binding within sessions”

MCP session management for Metorial. Provides session handling and tool lifecycle management for Model Context Protocol.

Unique: Binds tool lifecycle directly to session phases using hook-based architecture rather than requiring manual resource management in tool handlers. Tools declare their dependencies and cleanup requirements upfront, enabling the session manager to orchestrate initialization order and cleanup sequencing.

vs others: More integrated than generic tool registries (like LangChain's ToolKit) because it couples tool lifecycle to session state, ensuring deterministic resource cleanup rather than relying on garbage collection or manual teardown.
