kvault

What it does

kvault is a fast, local-first knowledge base that stores information as Markdown, JSON, or plain text. It allows users to build a personal or team knowledge corpus with powerful search capabilities, including ripgrep for speed and Tantivy for BM25 ranked fuzzy matching, without relying on external AI embeddings APIs.

Tools

• search_knowledge: Search the corpus for matching documents using keyword or BM25 ranking.
• list_knowledge: List all documents, with optional category filtering.
• get_document: Retrieve the full content of a specific document by its path.
• add_knowledge: Programmatically add new documents to the knowledge base.

Installation

Install ripgrep first, then install kvault: cargo install kvault

To enable MCP support, build with the mcp feature: cargo build --release --features mcp
