Pinako AI Bridge

Connect your browser tabs and libraries to Claude Desktop, Cursor, and everything else your AI can reach.

The Model Context Protocol (MCP) bridge that connects Pinako — a Chromium extension for tab tree management — to local AI clients including Claude Code, Claude Desktop, Cursor, Windsurf, Antigravity, Cline, Roo Code, Continue.dev, and any HTTP MCP client.

The bridge runs as a small native messaging host on your computer and exposes your Pinako tab tree, libraries, library groups, Main Notes, and browser bookmarks as MCP tools. It is a full read and write surface: your AI assistant can both query your browser state and reorganize it — move and nest tabs, create libraries, groups, and folders, edit titles, tags, memos, colors, and notes, find and remove duplicates, and apply large batched edits as a single undoable step.

Because the bridge runs inside desktop AI clients like Claude Desktop, Cursor, and Codex, the same assistant can move information between Pinako and the other tools, files, and services it connects to. For example:

• "Copy this research library's notes into a Google Doc."
• "Build a spreadsheet from the tabs in my Competitors library."
• "Visit the URLs in my Reading library and write up a summary."
• "Organize my open tabs into libraries by topic, then tag the work ones."
• "Find and remove my duplicate bookmarks."

Writes go through the same tier gating, confirmation, and undo machinery as the extension's own UI. Destructive operations (deletes, bookmark reorders) return a CONFIRMATION_REQUIRED result until the caller explicitly confirms, and a bulk_apply batch applies atomically as one undo step. Every write returns a structured {ok, error} result so clients can branch on the error code.

Tools

Read and write MCP tools. Full per-tool reference with parameters: pinako.pro/docs/ai-connect.

Read — query the tree, libraries, notes, and bookmarks, and search

get_tree, get_tree_summary, search_tabs, search_pinako, search_docs, list_libraries, get_library, get_main_tree_notes, get_bookmarks, list_browsers, find_duplicates

Tree structure — move, nest, group, and remove nodes

move_node, indent_node, outdent_node, create_group, create_folder, ghost_node, delete_node, delete_live_node, bulk_apply (up to 250 atomic sub-ops, undoable as one step)

Node metadata — titles, tags, memos, colors

set_title, set_tags, add_tags, remove_tags, set_memo, set_star_color, set_row_color

Libraries and library groups — create, edit, delete, and arrange

create_library, add_to_library, set_library_title, set_library_description, delete_library, create_library_group, set_library_group_title, set_library_group_description, delete_library_group, add_library_to_group, remove_library_from_group, reorder_library_panel, reorder_libraries_in_group

Notes — create and edit Main Notes and library notes

create_note, set_note_content, delete_note

Bookmarks — write to the browser bookmark tree

add_to_bookmarks (bookmark reads use get_bookmarks; dedup uses find_duplicates)

The read tools are safe to auto-approve. Write tools are individually annotated (idempotent, non-idempotent, or destructive) so MCP clients can gate them appropriately.

Install

Setup guide with screenshots and per-client instructions: pinako.pro/docs/ai-connect

Downloads: pinako.pro/downloads

Available installers:

• Windows — graphical installer (.exe)
• Linux x64 and Linux ARM64 — CLI installer

Requirements

• Pinako extension installed in your browser (Chrome Web Store)
• An active Pinako subscription (Pro or higher) — the bridge is gated by subscription

Build from source

git clone https://github.com/teleomorph/pinako-mcp.git
cd pinako-mcp
npm install
node setup/build.js --all

Outputs land in dist/. See setup/build.js for build flags (--all, --no-tauri, --no-cli).

The Tauri GUI installer can only be built on the platform it targets (i.e. build the Windows installer on Windows). The CLI installer cross-compiles for all listed platforms from any host.

Architecture

• host.js — MCP server / Chrome native messaging host
• setup/main.js — CLI installer (writes the native messaging host JSON, configures supported AI clients)
• setup/build.js — multi-stage build (esbuild → pkg → Tauri)
• installer/src-tauri/ — Rust Tauri GUI installer for Windows
