MCP Servers

obsidian-mcp

MCP server that provides read and write access to an Obsidian vault by interacting directly with markdown files on disk. Supports searching, listing, reading, creating, editing, and appending notes without requiring any Obsidian plugins.

README

obsidian-mcp

A small Model Context Protocol server that gives an MCP client (such as Claude Code or Claude Desktop) read and write access to an Obsidian vault by working directly on the markdown files.

No Obsidian plugins required and the app does not need to be running — the server reads and writes the .md files on disk.

Features

Works directly on the vault's files (no Local REST API plugin needed).
Path-traversal safe: every path is resolved inside the vault; ../ escapes are rejected.
Ignores .obsidian, .git, .trash and node_modules.

Tools

Tool	Description
`search_notes`	Full-text search across all notes, with line snippets
`list_notes`	List notes in the whole vault or a subfolder
`read_note`	Read a note by its vault-relative path
`create_note`	Create a new note (creates folders; won't overwrite unless asked)
`edit_note`	Replace an exact string in a note (`replace_all` optional)
`append_note`	Append text to the end of a note

Requirements

Node.js >= 18

Installation

git clone https://github.com/C0d1g0v3c/obsidian-mcp.git
cd obsidian-mcp
npm install

Configuration

The server requires the OBSIDIAN_VAULT environment variable: the absolute path to your vault. It exits with an error if it is not set.

Usage with Claude Code

claude mcp add obsidian --scope user \
  -e OBSIDIAN_VAULT="/absolute/path/to/your/vault" \
  -- node /absolute/path/to/obsidian-mcp/index.js

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

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

Running directly

OBSIDIAN_VAULT="/absolute/path/to/your/vault" node index.js

The server communicates over stdio and is meant to be launched by an MCP client.
