README

Obsidian MCP Server

An MCP server that lets Claude (and other MCP clients) read, write, search, and manage an Obsidian vault as a native tool. Local filesystem access only, no cloud sync.

Tools

Tool Description Read-only
obsidian_read_note Read a note's full markdown content yes
obsidian_write_note Create or overwrite a note (refuses overwrite unless asked) no
obsidian_append_to_note Append markdown to a note, creating it if missing no
obsidian_list_notes List notes in the vault or a folder yes
obsidian_search_vault Case-insensitive full-text search with line context yes
obsidian_read_frontmatter Parse a note's YAML frontmatter as structured data yes
obsidian_resolve_wikilinks Extract and resolve [[wikilinks]] to vault files yes

All paths are relative to the vault root. The .md extension is optional. Paths are validated to stay inside the vault (no directory traversal).

Setup

npm install
npm run build

The vault location is set with the OBSIDIAN_VAULT_PATH environment variable. If unset, it defaults to ~/Obsidian.

Configure in an MCP client

Add to your client's MCP config (example for a stdio client):

{
  "mcpServers": {
    "obsidian": {
      "command": "node",
      "args": ["/path/to/obsidian-mcp-server/dist/index.js"],
      "env": {
        "OBSIDIAN_VAULT_PATH": "/path/to/your/vault"
      }
    }
  }
}

Develop

npm run dev        # run from source with tsx
npm run typecheck  # type-check without emitting
npm run inspect    # launch the MCP Inspector against the server

Roadmap

  • Semantic/vector search (embed notes, query by meaning)
  • Dataview query passthrough
  • Template-aware note creation
  • Backlink graph traversal
