Vault Health Mcp

Scans your Obsidian vault for structural rot and optionally fixes it. The free tier gives you detection tools: broken wikilinks, orphaned notes, missing frontmatter, and vault-wide statistics. The Pro tier adds `repair_vault`, which makes additive-only changes like converting broken links to plain text and adding default YAML frontmatter blocks. No deletions, no content removal. License verification happens offline via JWT. Useful when you've let a vault grow organically for months and want to clean up link decay without manually hunting through hundreds of notes. Works with any Obsidian vault, no plugins required on the Obsidian side.
