Bookmark MCP Server

A simple MCP (Model Context Protocol) server that lets Claude Code save, find, and list bookmarks. Bookmarks are stored in a JSON file at ~/bookmarks/bookmarks.json.

Parameters:

• title (string) — the name of the bookmark
• url (string) — the URL to bookmark

get_bookmark

Finds a bookmark by title using a case-insensitive search.

Parameters:

• title (string) — the title to search for

Per-project setup

Add a .mcp.json file to your project root:

{
  "mcpServers": {
    "bookmark-server": {
      "command": "node",
      "args": ["index.js"],
      "cwd": "/path/to/my-first-mcp"
    }
  }
}

Global setup

To make the server available in every Claude Code session, add it to ~/.claude/settings.json:

{
  "mcpServers": {
    "bookmark-server": {
      "command": "node",
      "args": ["/path/to/my-first-mcp/index.js"]
    }
  }
}
