Aggregates multiple MCP servers behind a single, secure endpoint with unified tool/resource discovery, OAuth authentication, and resilient request routing. Enables users to manage and interact with multiple MCP backends through one centralized interface with load balancing and circuit breakers.
mcp-aggregator is a single MCP server that fans out to multiple backend MCP servers and re-exposes all their tools through one streamable-HTTP endpoint, with namespacing to avoid collisions, per-backend isolation for fault tolerance, and a REST side-channel for live health and tool catalogs.
Acts as an MCP gateway aggregating multiple child MCP servers into a single namespaced interface, with an optional memory layer that caches tool results to reduce redundant calls.
