Markdown Vault MCP

Point this at any folder of Markdown files and you get a 30-tool MCP server that turns your notes into queryable context. It combines SQLite FTS5 full-text search with semantic vector search (FastEmbed, Ollama, or OpenAI), handles YAML frontmatter indexing, and exposes read, write, edit, delete, and rename operations with automatic incremental reindexing. The adaptive chunking splits long sections at progressively deeper heading levels until they fit a configurable word budget, and search returns sentence-scale snippets by default to keep context costs bounded. Ships with optional Git auto-commit, OIDC auth for HTTP deployments, and 6 prompt templates including one that scans recent notes and proposes missing wikilinks. Useful for Obsidian vaults, Zettelkasten collections, or any documentation folder you want Claude to search and modify in conversation.
