Nexus

grafbase/nexus

Nexus aggregates multiple MCP servers, APIs, and LLM providers (OpenAI, Anthropic, Google, AWS Bedrock) through a single unified endpoint, enabling tool discovery via context-aware fuzzy search and routing requests across the entire AI stack. The server supports multiple MCP protocols (STDIO, SSE, HTTP), provides security features including CORS, CSRF protection, OAuth2, and TLS, and includes rate limiting with in-memory or Redis backends. Nexus solves the problem of managing disparate AI infrastructure by consolidating governance, control, and orchestration into one TOML-configured router available as a binary, Docker container, or buildable from source.
