Agent Search MCP
Connect multiple search sources through one MCP service, choose engines, and combine results.
An engine registry, tool-level engine selection, and fused ranking bring multiple sources into one MCP service. Engines remain replaceable and results inspectable.
Agents search repeatedly, and every engine has trade-offs in coverage and cost. I wanted control over source selection and cross-checking.
The open-source service and npm package are published. An external integration PR and the architecture review it prompted are documented in an article.
