Kong/kong
Kong Gateway is a cloud-native, scalable API gateway that manages API, AI LLM, and Model Context Protocol (MCP) traffic with advanced security, observability, and extensibility features.
portel-dev/ncp
NCP, the Natural Context Provider, aggregates MCP servers and solves a problem that grows with the number installed: every tool definition occupies context, and a client presented with hundreds of tools both wastes tokens and chooses worse. NCP exposes itself as a single MCP server and indexes the tools of every configured backend with vector search, so a request retrieves the handful of relevant tools instead of the whole catalogue — described in the README as smart loading, and the reason it claims token and energy savings. Tools are loaded on demand rather than all at connect time. It also supports running tools on a schedule, which turns it from a proxy into something that can perform recurring work without a client attached. It acts as both an MCP server and an MCP client, which is what an aggregator must be, and is documented against Claude Desktop, Gemini and OpenAI clients. Distribution is npm as @portel/ncp plus .dxt desktop-extension releases, and it is registered as io.github.portel-dev/ncp. The licence is Elastic 2.0 rather than a standard open-source licence, which is worth checking before commercial deployment. The audience is people with many MCP servers configured who are hitting context limits or noticing degraded tool selection.
