vault-index
Local hybrid keyword + vector search (SQLite FTS5 + sqlite-vec) over markdown vaults and code.
What it does
vault-index is an MCP server, a connector that lets an AI assistant use it as a tool. It is installed locally as a package and runs on your machine.
From the publisher's description, Electra Index matched it to 2 capabilities: knowledge base qa and sql querying. That makes it a candidate for tasks such as query databases in plain language or answer customer questions.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.
