Obsidian-MCP-For-Cursor

MCP server for Obsidian vaults, optimised for Cursor agents — safe note editing, lean tool surface, direct filesystem access.

Forked from @istrejo/obsidian-mcp (MIT) with Cursor-specific enhancements.

Features

• 10 agent-focused tools — no unused move_note, search_by_tags, or get_graph

• Safe writes — patch and replace_section modes so agents cannot accidentally truncate notes with partial replace

• Token-AND search — multi-word vault search requires all terms to appear in a note

• Optimistic concurrency — contentHash on read, optional expectedHash on write

Tools (v1)

Requirements

• Node.js >= 20

• An Obsidian vault path via OBSIDIAN_VAULT_PATH

Setup

git clone https://github.com/JeddowesF/Obsidian-MCP-For-Cursor.git
cd Obsidian-MCP-For-Cursor
npm install
npm run build
npm test

Cursor configuration

Copy the relevant section from examples/cursor-mcp.json into ~/.cursor/mcp.json:

{
  "mcpServers": {
    "obsidian": {
      "command": "node",
      "args": ["/absolute/path/to/Obsidian-MCP-For-Cursor/dist/index.js"],
      "env": {
        "OBSIDIAN_VAULT_PATH": "/absolute/path/to/your/vault",
        "PATH": "/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin"
      }
    }
  }
}

Reload the Cursor window after saving.

Safe write workflow

1. Read the note — note the contentHash in the response.

2. Edit using the safest mode:

   • patch — find/replace a unique substring (old_string / new_string)

   • replace_section — replace content under a heading (heading + content)

   • append / prepend — add content without touching existing body

   • replace — full body overwrite only; blocked if new body < 50% of existing unless force: true

3. Pass expectedHash from step 1 to detect concurrent edits.

Example: patch a line

{
  "path": "Projects/my-project",
  "mode": "patch",
  "old_string": "status: draft",
  "new_string": "status: done"
}

Example: replace a section

{
  "path": "Projects/my-project",
  "mode": "replace_section",
  "heading": "Next steps",
  "content": "- Ship v1\n- Write docs"
}
