Grafbase just launched Nexus, an open-source AI Router that unifies MCP servers and LLMs through a single endpoint. Designed for enterprise-grade governance, control, and observability, Nexus helps teams manage AI complexity, enforce policies, and monitor performance across their entire stack.
Built to work with any MCP server or LLM provider out-of-the-box, Nexus is designed for developers who want to integrate AI with the same rigor as production APIs.
Here are a few key differentiators vs LiteLLM today:
- Nexus does MCP server aggregation and LLM routing - LiteLLM only does LLM routing
- The Nexus router is a standalone binary that can run with minimal TOML configuration and optionally Redis - LiteLLM is a whole package with dashboard, database etc.
- Nexus is written in Rust - LiteLLM is written in Python
That said, LiteLLM is an impressive project, but we're just getting started with Nexus so stay tuned for a steady barrage of feature launches the coming months:)
Seems quite similar to the commercial nexos.ai platform, which also focuses on routing, governance, and observability for AI workloads, but as a proprietary solution rather than open source
I'm curious, what issue does that solve? I'm only working on agents that make tool calls via HTTP in a home baked way but I can't imagine how resolving the tools from 2 MCP servers is harder than 1.

Nexus name already has a taker
