Common questions

Is Synchronity safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.21) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Synchronity

Shop anything online with AI — search, compare, and buy across connected stores from any AI assistant.

Synchronity is commerce infrastructure for AI assistants. It connects to the hosted Synchronity gateway at https://api.synchronity.app — there is nothing to self-host.

This repository contains the public, MIT-licensed pieces:

Part	What it is
`packages/mcp`	The MCP server — exposes shopping tools to Claude, Cursor, and any MCP client
`packages/sdk`	Typed gateway client used by the MCP server
`desktop-extension`	Claude Desktop extension (`.mcpb`) source — a zero-dependency bridge to the gateway
`plugins/synchronity`	Cross-assistant plugin (Claude Code + Codex) — install via the marketplace below
`woocommerce`	The Synchronity WooCommerce plugin — makes a store agent-ready

Releases attach prebuilt artifacts: the `synchronity.mcpb` desktop extension and the WooCommerce plugin zip. See Releases.

For shoppers — connect your AI assistant

Claude Desktop (easiest)

Download `synchronity.mcpb` from the latest release (or from api.synchronity.app/setup/download).
Open it with Claude Desktop and click Install.
Ask Claude to shop — e.g. *"Search Synchronity for a wireless keyboard."*

Claude Code (plugin marketplace)

/plugin marketplace add themewireco/synchronity

/plugin install synchronity@synchronity

Then just shop — *"find me a birthday cake from my stores"*. The plugin bundles the synchronity-commerce skill and runs the MCP server locally via npx, so there is nothing to clone or build.

Codex

Add the Synchronity plugin from this repo (plugins/synchronity). Codex reads .codex-plugin/plugin.json and connects to the hosted MCP at https://api.synchronity.app/mcp, with the same synchronity-commerce skill.

Any MCP client (manual)

npm install && npm run build

"mcpServers": { "synchronity": { "command": "node", "args": ["/absolute/path/to/synchronity/packages/mcp/dist/index.js"], "env": { "GATEWAY_URL": "https://api.synchronity.app" } } } }

GATEWAY_URL defaults to https://api.synchronity.app. Sensitive actions (checkout, payment) require buyer approval — the assistant walks you through a one-time approval step.

What the assistant can do

Product search & details (with inline images), compare across stores, reviews, cart management, shipping, checkout, card/mobile-money payment, order tracking, and human-in-the-loop approval for sensitive actions.

For merchants — make your WooCommerce store agent-ready

Download the WooCommerce plugin zip from the latest release.
In WordPress: Plugins → Add New → Upload Plugin, choose the zip, Install and Activate.
Open WooCommerce → Synchronity, copy your connector key, and register your store with Synchronity.

Your store keeps its own catalog, currency, shipping, and orders — Synchronity routes agent requests to it through the gateway.

Build the artifacts yourself

npm run build         # build the MCP server + client

npm run build:mcpb # -> synchronity.mcpb (Claude Desktop extension) npm run build:plugin # -> synchronity-woocommerce-v .zip

Configuration

Env var	Default	Purpose
`GATEWAY_URL`	`https://api.synchronity.app`	Synchronity gateway base URL
`DEFAULT_SITE_ID`	—	Optional default store to scope tools to
`DEBUG`	`false`	Verbose logging to stderr
