MCP Servers

obsidian-connector

A local MCP connector that lets Claude read, write and search any Obsidian vault directly from disk.

README

Vault Connector for Obsidian

A local MCP connector that lets Claude read, write and search any Obsidian vault. It works directly with the Markdown files on disk — no community plugins, and Obsidian does not need to be running.

Independent project, not affiliated with or endorsed by Obsidian. "Obsidian" is a trademark of Dynalist Inc.

All access is sandboxed to the single vault folder you configure; the server refuses any path that would escape it.

`list_notes`	read	List Markdown notes, optionally within a folder
`list_folders`	read	List sub-folders of the vault or a folder

`search_notes`	read	Text or regex search, with `#tag` and path-glob filters
`list_tags`	read	List every tag in the vault with usage counts
`get_backlinks`	read	Find notes linking to a target via `[[wikilinks]]`

`move_note`	write	Move/rename a note and rewrite `[[wikilinks]]` to it

`read_periodic_note`	read	Read a daily, weekly or monthly note

Also exposes MCP prompts (summarize_note, daily_review) and a resource (obsidian://vault/structure) describing the vault layout.

Configuration

The server is configured through environment variables (set automatically from the connector settings when installed as a Desktop Extension):

Variable	Required	Default	Purpose
`OBSIDIAN_VAULT_PATH`	yes	—	Absolute path to the vault folder
`OBSIDIAN_DAILY_FOLDER`	no	`` (root)	Vault-relative folder for daily notes
`OBSIDIAN_DAILY_FORMAT`	no	`YYYY-MM-DD`	Daily-note filename format
`OBSIDIAN_WEEKLY_FOLDER`	no	daily folder	Folder for weekly notes
`OBSIDIAN_WEEKLY_FORMAT`	no	`YYYY-[W]WW`	Weekly-note format (`WW` = ISO week; `[..]` = literal)
`OBSIDIAN_MONTHLY_FOLDER`	no	daily folder	Folder for monthly notes
`OBSIDIAN_MONTHLY_FORMAT`	no	`YYYY-MM`	Monthly-note filename format
`OBSIDIAN_TEMPLATES_FOLDER`	no	`` (root)	Folder holding note templates

Development

npm install
npm run build         # compile TypeScript to dist/
npm run inspect       # open the MCP Inspector against the server

Try it locally in Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "obsidian": {
      "command": "node",
      "args": ["/absolute/path/to/dist/index.js"],
      "env": {
        "OBSIDIAN_VAULT_PATH": "/absolute/path/to/your/Vault",
        "OBSIDIAN_DAILY_FOLDER": "Log"
      }
    }
  }
}

Package as a Desktop Extension (`.mcpb`)

npm run pack          # builds and produces obsidian-connector.mcpb

The resulting .mcpb can be installed in Claude Desktop with one click, or submitted to the Claude connector directory via the Desktop Extension submission form.
