MCP servers for vector databases

Query and manage the store underneath your embeddings.

This is the storage layer a RAG setup sits on: Pinecone, Qdrant, Chroma, Weaviate, Milvus, or Postgres with pgvector. The servers here mostly wrap one vendor's client, so the thing that varies is not the search quality, it is how much of your instance a single key can reach.

Before you install one

Three things that separate the servers here, none of which shows up in a description.

Is the key scoped to one index?
Most of these servers take an account-level key and expose every collection on the instance. A key scoped to one index is the difference between a bad query and a wiped production index, and the vendor, not the server, is where you set that.
Local or hosted?
Chroma and Qdrant both run on your own machine. A local one keeps the vectors on disk, needs no key at all, and cannot leak an index to anyone. It is the right default for anything you would not publish.
Which write tools come with search?
Upsert and delete usually live in the same server as query. If you only need retrieval, a server that exposes only retrieval is a smaller thing to get wrong.

Every listing below has a scan report saying what the server asks for and what it does with it. The rubric is on how we grade.

The vector database servers we would look at first

Reviewed servers rank first, then the ones with real adoption. At most two per publisher, so no account can fill the list. Nothing here is sponsored.

Or try them without installing any

Add the gateway once and your agent runs search "pinecone", reads the grades, and calls the one it picks. Nothing to install per server, and an F-graded server cannot be reached through it.
