Selling

Use Sling with Claude and Codex

Connect Claude or Codex to Sling and ask about your store in plain words. Bigger changes and payments wait until you confirm them yourself at Sling, unless you chose otherwise.

Sling is software, not a bank. Accounts, balances, cards and payouts are provided by our payment partners and their banks under their terms.

What it can do today

  • Read your store: its name, currency, time zone and your role in it.
  • Read your orders, one at a time or as a list, and your sales figures for a period. They are the same figures as Analytics.
  • Read your offers: discount codes, order bumps, upsells, post purchase offers, gifts, volume tiers and bundles, with how often each one was taken.
  • Read your A/B tests and where each one stands.
  • Read your checkout design and whether an unpublished draft is waiting.
  • Look things up in these help articles.
  • For the owner of a Sling account: an overview of the account with its balances, the steps it still needs, and its latest transfers and payouts.

An app works with what you let it see. A teammate's app sees what the teammate's role opens, nothing more. Sales figures and A/B results need an active plan.

What waits for you

An app connected to Sling never confirms anything for you. Small changes, such as pausing an offer, apply at once. Bigger ones wait until you confirm them yourself at Sling, in your own browser: deleting something, large or unlimited discounts, free gifts, upsells, shipping prices and renaming the store. Payments wait for you unless you chose otherwise: under MCP in your account, Move money can be Not allowed, Ask me first (the code from your authenticator app on every payment, the default) or Automatic. Automatic sends transfers to your own stores and payouts to your own saved payout methods at once, within 500 USD per payment and 2,000 USD in 24 hours, fees included, and at most 10 payments sent automatically in 24 hours, and you switch it on only after two warnings and your code. Paying anyone else always waits for you.

Connect Claude

  1. Open your account, choose MCP in the sidebar and find Connect Claude or Codex. Copy the server URL, https://app.sling.cx/mcp.
  2. In Claude, open Customize and then Connectors. On some versions it sits under Settings.
  3. Choose Add custom connector, name it Sling and paste the server URL.
  4. Sign in to Sling when Claude asks.
  5. Pick the store, choose what the app may do and press Allow.

Using Claude Code? The Claude tab shows one command to copy. Run it in your terminal, then type /mcp in Claude Code and sign in to Sling.

Connect Codex

  1. Open your account and choose MCP in the sidebar. Under Connect Claude or Codex, open the Codex tab.
  2. Open ~/.codex/config.toml and add a line [mcp_servers.sling], with the line url = "https://app.sling.cx/mcp" under it.
  3. Run codex mcp login sling in your terminal.
  4. Sign in to Sling in the browser window that opens, pick the store and press Allow.

One store or your account

Each connection is for one store or for your Sling account, never both. To use an app with two stores, connect it twice. Only the owner of a Sling account can connect the account itself.

Disconnect an app

  1. Open your account, choose MCP in the sidebar and find Connected apps.
  2. Press Revoke next to the app.

The app stops at its very next request. A store owner sees every app connected to the store and can revoke any of them. A teammate sees the apps they connected themselves.

Removing Sling inside Claude or Codex alone does not end the connection at Sling. Revoke it under Connected apps as well.

Opening store by store

Connecting Claude or Codex is being rolled out. If MCP is not in your account sidebar yet, it is not open for your store yet.
