MCP Semantic Retrieval Embedding Tools

MCP servers that implement semantic search and RAG capabilities for specific data sources (codebases, web content, documentation, macroeconomic data). Does NOT include general RAG frameworks, vector databases, embedding models, or non-MCP semantic search tools.

There are 22 mcp semantic retrieval tools tracked. The highest-rated is userFRM/rpg-encoder at 42/100 with 20 stars.
