Wassel connects the AI agent you already use to Shopify and the rest of your regional stack. Here is how to get running.
Quickstart
Four steps from signup to your first agent action. The whole thing takes about five minutes.
Sign up for a free Wassel workspace. No card required.
Open Install, pick your client — Claude Desktop, Claude Code, Cursor, n8n, or any MCP client — and follow the steps. Claude Desktop signs in through your browser; other clients use a workspace key.
Open Apps and connect the services your agent should act on — Shopify, shipping, payments, messaging, accounting. Each connection asks only for the permissions its tools need.
Ask your agent something plain, like "list my last 5 Shopify orders." Every call your agent makes shows up in Logs in real time.
Connect your agent — the actual config
Your workspace gets a unique MCP endpoint and API key (shown on the Install page after signup). These are the exact shapes, with placeholders:
https://api.wassel.cloud/mcp Paste that URL, approve the Wassel sign-in tab that opens. No API key needed — auth runs through your browser.
claude mcp add --transport http wassel https://api.wassel.cloud/mcp/<YOUR_WORKSPACE_ID> --header "Authorization: Bearer <YOUR_WASSEL_KEY>"
{
"mcpServers": {
"wassel": {
"url": "https://api.wassel.cloud/mcp/<YOUR_WORKSPACE_ID>",
"headers": { "Authorization": "Bearer <YOUR_WASSEL_KEY>" }
}
}
}Your agent then sees three tools: WASSEL_SEARCH_TOOLS (find the right tool for a job), WASSEL_MANAGE_CONNECTIONS (list and connect apps), and WASSEL_EXECUTE_TOOL (run one). Three tools instead of hundreds keeps your agent's context small.
No MCP? Plain REST works
curl -X POST https://api.wassel.cloud/v1/tools/bosta/list_deliveries -H "Authorization: Bearer <YOUR_WASSEL_KEY>" -H "Content-Type: application/json" -d '{ "limit": 5 }'The full tool surface is public: api.wassel.cloud/openapi.json — every integration, every tool, full input schemas. Point your agent framework at it directly if you prefer codegen.
How it works
Wassel is a real-time pass-through. Your agent connects to one secure endpoint; Wassel turns each request into a real API call to the connected service, returns the result, and keeps no copy of your data. One instruction can span tools — for example, when a Shopify order is paid, book a shipment and send the customer a tracking link.
Connecting an agent and connecting an app are two separate steps. The agent connection is how your AI talks to Wassel. App connections are the services Wassel is allowed to act on for you.
Security
Access tokens are encrypted at rest, traffic runs over TLS, and every connection uses the least permissions its tools need. You can revoke any connection at any time. Full detail is on the Security page.
Integrations
Wassel ships connectors across shipping, payments, messaging, e-commerce, accounting, tax, and marketing. New connectors are added regularly.
