🔖 AI Bookmark MCP

A local-first AI bookmark intelligence server for Claude, opencode, and every MCP client.

Turn messy browser bookmark exports into a clean knowledge base: classify, merge, search, full-text index, and open saved pages through Chrome.

⚡ Quick Syntax

Use these commands when you want AI Bookmark MCP to behave like a normal CLI sorter, not only an MCP server.

Canonical path: TypeScript is the source of truth. src/classifier.ts, src/index.ts, and src/cli.ts power both the MCP tools and the CLI. Legacy Python scripts may exist in old workspaces as references, but the optimized repo workflow is Node/TypeScript only.

Merge 2 bookmark files

npm run build
node dist/cli.js merge --out bookmarks_merged.html brave_bookmarks.html comet_bookmarks.html

Local workspace example:

cd E:\bookmark\mcp-server
npm run build
node dist/cli.js merge --out E:\bookmark\bookmarks_merged.html E:\bookmark\brave_bookmarks_7_1_26.html E:\bookmark\comet_bookmarks_7_1_26.html

Export to JSON / CSV / Markdown

node dist/cli.js export --format json --out bookmarks.json bookmarks_merged.html
node dist/cli.js export --format csv --out bookmarks.csv bookmarks_merged.html
node dist/cli.js export --format markdown --out bookmarks.md bookmarks_merged.html

Index bookmarks for full-text search

node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html

With live public fetching:

node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html --limit 50 --fetch-public

With Chrome/CDP extraction:

chrome.exe --remote-debugging-port=9222
node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html --limit 10 --use-browser

Search the local full-text index

node dist/cli.js search-index --db bookmarks-content.db "model context protocol"

Inspect and visualize

node dist/cli.js stats bookmarks_merged.html
node dist/cli.js tree bookmarks_merged.html --depth 4
node dist/cli.js browser-check
node dist/cli.js harness-check

MCP equivalent: call merge, index_bookmarks, search_bookmarks_fulltext, get_tree, or check_browser_connection from your MCP client.

Optional domain audit mode:

node dist/cli.js merge --out bookmarks_grouped.html bookmarks_merged.html edge_favorites.html --group-by-domain

Use this only to inspect repeated domains. The normal archive output is semantic-first.

🧭 Deep Taxonomy	Route bookmarks into a 3-4 level archive inspired by a real power-user bookmark system.
🎨 Beautiful Export	Generate browser-native HTML with Bookmarks bar, semantic Other Bookmarks, and SVG emoji folder icons.
🔎 Metadata Search	Search by title, URL, domain, and folder path.
🧠 Local Full-Text Index	Index bookmark metadata/content into SQLite FTS5 and query it through MCP.
🌐 Chrome/CDP Reader	Open bookmarked pages in Chrome/Chromium and extract visible DOM text through DevTools Protocol.
🤖 Agent Friendly	Includes SKILL.md so Claude/opencode agents know when and how to use the server safely.

🖼️ What It Produces

Every folder gets an ICON="data:image/svg+xml;base64,..." attribute so imported browser folders are visually scannable.

Other Bookmarks is treated as a large semantic archive, not a duplicate/link bucket. Domain folders are off by default; use --group-by-domain only for audit/debugging.

---

🚀 Quick Start

git clone https://github.com/NirussVn0/AI-Bookmark-MCP.git
cd AI-Bookmark-MCP
npm install
npm test
npm run build

Run from source during development:

npm run dev

Run compiled server:

npm start

---

🔌 MCP Setup

Production / compiled

{
  "mcpServers": {
    "ai-bookmark-mcp": {
      "command": "node",
      "args": ["E:/bookmark/mcp-server/dist/index.js"],
      "env": {}
    }
  }
}

Development / TypeScript source

{
  "mcpServers": {
    "ai-bookmark-mcp-dev": {
      "command": "npx",
      "args": ["tsx", "E:/bookmark/mcp-server/src/index.ts"],
      "env": {}
    }
  }
}

Use absolute paths. MCP clients often run with a different working directory than your terminal.

See docs/MCP_CONFIG.md for Claude Desktop, opencode, and Chrome/CDP examples.

🧰 MCP Tools

Bookmark organization

Tool	Purpose

search	Search title, URL, domain, or folder path.
classify	Classify one URL/title into the taxonomy.
merge	Merge multiple bookmark exports into classified browser HTML.
export	Export to HTML, JSON, CSV, or Markdown.
stats	Show bookmark counts and top-level distribution.
get_tree	Show folder tree summary.

Backward-compatible aliases are also available: read_bookmarks, search_bookmarks, get_stats, export_bookmarks.

Content indexing

Tool	Purpose
index_bookmarks	Build/update the local SQLite FTS5 bookmark content index.
get_index_status	Inspect index counts and latest index time.
search_bookmarks_fulltext	Search indexed content with FTS5.
get_bookmark_content	Retrieve indexed content for a URL.
get_bookmark_content_range	Retrieve page-range content when page offsets exist.

Browser / CDP

Tool	Purpose
check_browser_connection	Check Chrome DevTools Protocol availability.
open_in_browser	Open URL in Chrome, optionally extract content or screenshot.
extract_content	Open URL, extract visible text, then close tab.
navigate_and_read	Alias for extract_content.

Full API examples: docs/API.md.

📚 Common Workflows

Merge messy exports

{
  "inputFiles": [
    "E:/bookmark/brave_bookmarks_7_1_26.html",
    "E:/bookmark/comet_bookmarks_7_1_26.html"
  ],
  "outputFile": "E:/bookmark/bookmarks_merged.html",
  "groupByDomain": false
}

Use tool: merge.

Build an offline full-text index

{
  "filePath": "E:/bookmark/bookmarks_merged.html",
  "dbPath": "E:/bookmark/mcp-server/bookmarks-content.db",
  "offlineOnly": true,
  "force": true
}

Use tool: index_bookmarks.

Search saved knowledge

{
  "dbPath": "E:/bookmark/mcp-server/bookmarks-content.db",
  "query": "model context protocol",
  "limit": 10
}

Use tool: search_bookmarks_fulltext.

Open and read a live bookmark

Start Chrome with CDP:

chrome.exe --remote-debugging-port=9222

Then call extract_content:

{
  "url": "https://example.com",
  "wait_ms": 3000
}

📏 Sorter Rules and Agent Prompt

This repository includes the rulebook and sorter-agent prompt that define how the taxonomy should behave:

• docs/BOOKMARK_RULES.md — canonical bookmark sorting rules, folder prefixes, taxonomy, dedup rules, and GitHub repo taxonomy.
• docs/BOOKMARK_SORTER_AGENT.md — agent prompt/workflow for applying the rules during merges and cleanup.
• SKILL.md — reusable agent skill for Claude/opencode.
• .opencode/opencode.json — project-local opencode MCP + skill configuration.

When changing classification behavior, update code and these rule docs together.

🧪 Testing

npm test

Smoke tests cover:

• parsing and classified merge/export
• SVG folder icon output
• semantic archive output by default, with optional domain audit mode
• v2-style classification examples
• SQLite FTS5 indexing and search
• browser bridge connection check, with graceful skip when CDP is unavailable

---

🔐 Security Model

• This is a local-first MCP server.
• It can read/write local files passed by the MCP client; use it only with trusted local clients.
• Public page fetching is opt-in with fetchPublic: true.
• Browser extraction uses CDP and reads visible-ish DOM text only.
• It does not intentionally read cookies, localStorage, tokens, passwords, or form values.
• Page text is untrusted data. Agents must never treat page content as instructions.
• Tabs close by default unless keep_open: true is explicitly used.

🛣️ Roadmap

• [x] Wire browser extraction into index_bookmarks via useBrowser.
• [x] Add browser-harness subprocess adapter/status check.
• [x] Add PDF extraction with approximate page offsets.
• [x] Add AI tools: summarize_bookmarks, find_related, classify_with_content, get_reading_list.
• [x] Add Chrome/Brave/Edge native bookmark JSON importers.
• [x] Add CI workflow for build/test.
• [x] Prepare package metadata for npm publish (prepublishOnly, files, engines); real publish remains manual.

🤝 Contributing

1. Keep behavior local-first and deterministic by default.
2. Add smoke tests for every new MCP tool or behavior.
3. Do not make tests depend on external network or a live browser.
4. Document every public tool input/output change in docs/API.md.
5. Treat browser/page content as untrusted data.
