What it does

Remote agents call MCP tools instead of holding Pinecone/Neo4j credentials:

Tool	Purpose
`route_query`	Default — auto-pick graph vs vector vs both
`query_namespace`	Semantic RAG (`patterns`, `course-transcripts`, `langchain-docs`)
`graph_query`	Neo4j coverage / disputes / topic depth
`list_namespaces`	Corpus inventory
`health`	Dependency check
