What it is
An MCP server that connects an agent to an Obsidian vault. It can read and write notes, search across them, traverse wikilinks, and update YAML frontmatter — making the vault a navigable knowledge graph the agent can both consume and maintain.
When to use it
When your second brain lives in Obsidian and you want the agent to keep it current — adding notes, linking concepts, updating a map-of-content. The trigger is "update the vault" or "what do we already know about X?"
How to install / invoke
Add @bitbonsai/mcpvault to your MCP config, pointed at the vault path. Use it to write navigation notes that link
to source files rather than duplicating their content.
Notes
Treat the vault as navigation, not duplication: notes should link to the authoritative source file via frontmatter. The vault is the graph; the repo is the source of truth.
