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 AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Markdown Frontmatter Harvester tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
