Markdown Vault MCP

Markdown Vault MCP is an open-source Model Context Protocol (MCP) server and Python library that provides hybrid semantic and keyword search, reading, and editing capabilities for Markdown-based knowledge vaults, compatible with applications like Obsidian. It features advanced search (FTS5 + embeddings), YAML frontmatter filtering, git integration, backlink/outlink analysis, and detailed write/sync operations. Designed for individual users or small teams who want to let AI models like Claude access, search, and manage structured Markdown notes locally or on a server, it fits users hosting private knowledge bases and requires a single-vault-per-server setup.
