What is the Markdown Frontmatter Harvester MCP Server?
If you use a Knowledge Management system like Obsidian, Logseq, or Hugo, you likely use YAML 'frontmatter' at the top of your markdown files to track metadata like status: draft, tags: [idea, research], or date: 2024-01-01.
When you ask Claude, 'Which of my notes are marked as drafts and never published?', it fails because it can't read thousands of local files quickly. This MCP solves that by acting as a hyper-fast metadata librarian. It recursively scans your local folder, rips out only the YAML frontmatter from every file, and aggregates it into a clean JSON index. The AI can then instantly filter, sort, and query your entire knowledge base.
The Superpowers
- Vault-Wide Indexing: Turns scattered local markdown metadata into a unified database.
- Lightning Fast: Uses
fast-globandgray-matterto scan 1,000+ files in milliseconds. - Zero Config: Just give the AI the absolute path to your notes folder.
- 100% Air-Gapped Privacy: Your private journal entries and business notes never leave your machine.
Built-in capabilities (1)
Provide the absolute directory path. Scan a local directory of Markdown files (Obsidian/Hugo) and extract all YAML frontmatter tags, dates, and metadata

Frequently asked questions
Does it send my entire note content to the AI?
No. To protect your privacy and save context tokens, it strictly extracts ONLY the YAML metadata block between the --- delimiters. The actual body text of your note is ignored.
Will this alter my Obsidian files?
Not at all. The parser operates in a strict read-only mode. It reads the files into memory to extract the metadata and never writes back to the disk.
Does it work with nested folders?
Yes! The engine uses recursive globbing to scan every single folder and sub-folder inside the path you provide.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
