Nexus

Nexus is an AI router built by Grafbase that aggregates multiple MCP servers and LLM providers (OpenAI, Anthropic, Google Vertex AI) through a unified HTTP interface, transforming from a simple MCP router into a full-featured AI gateway. It features comprehensive rate limiting with token-based quotas, stateless JWT-based authentication, tool discovery via Tantivy search indexing, and support for both STDIO and HTTP MCP server protocols with OAuth2 token forwarding. The implementation includes Docker deployment, Redis-backed distributed rate limiting, bring-your-own-key functionality for secure API key management, and extensive integration testing, making it valuable for organizations needing centralized AI resource management, multi-tenant AI applications requiring usage controls, and enterprises seeking to aggregate diverse AI tools and models behind a single authenticated endpoint.
