Transport Agnostic Tool Registry With Multi Protocol Binding

via “transport-agnostic tool registry with multi-protocol binding”

A NestJS library for building transport-agnostic MCP tool services. Define tools once with decorators, consume them over HTTP, stdio, or directly via the registry. The documentation and examples generally focus one enterprise monorepos but can be easily a

Unique: Implements a unified registry abstraction that decouples tool definitions from transport implementation, allowing the same tool code to be served over HTTP, stdio, and direct in-process calls without modification — most MCP libraries require separate server implementations per transport

vs others: Eliminates transport-specific code duplication compared to building separate HTTP and stdio MCP servers, and enables easier testing via direct in-process tool invocation

MCP server: bk_mcp

Unique: unknown — insufficient data on transport implementation (e.g., whether it uses adapter pattern, middleware, or specific library choices)

vs others: Decouples MCP logic from transport details, enabling single server implementation to work across stdio, HTTP, and WebSocket without duplication
