Nothing serious here today

Today is the operative word: we check Swell every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

swell

swell_create_product

MUTATES LIVE STORE DATA. Create a new product in the store. Provide the common fields directly (name is required); anything else goes in `fields`, which is merged into the request body. Swell backend REST API: POST /products.

swell_get_customer

Fetch a single customer (Swell `accounts` model) by id. Supports `expand` and `fields`. Swell backend REST API: GET /accounts/{id}.

swell_get_order

Fetch a single order by its record id or its order number. Supports `expand` and `fields`. Swell backend REST API: GET /orders/{id}.

swell_get_product

Fetch a single product by its record id or its slug. Supports `expand` and `fields`. Swell backend REST API: GET /products/{id}.

swell_get_subscription

swell_list_coupons

List discount coupons, with filtering and sorting. Swell backend REST API: GET /coupons.

Power tool: read-only (GET only) access to ANY Swell model not covered by a dedicated tool — e.g. stock, promotions, giftcards, payments, shipments, settings. Supply the collection name plus the usual list params (limit, page, where, sort, expand, fields, search). Swell backend REST API: GET /{collection}.

swell_update_order

MUTATES A LIVE ORDER. Partially update an existing order by id — e.g. change status, fulfillment, or notes. Provide the id plus a `fields` object of attributes to change, e.g. {"status":"complete"}. Swell backend REST API: PUT /orders/{id}.

Swell — questions

Answers built from our own checks of this server.

What can Swell do?

It exposes 16 tools, read directly from the server on our last check. Among them: swell_create_product, swell_get_customer, swell_get_order, swell_get_product, swell_get_subscription, swell_list_carts and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Swell working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 173 ms. The bar chart above shows every period we have measured.

How do I connect Swell?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Swell need an API key?

No. Swell completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Swell?

It answers our handshake in 173 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Swell open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
