@yawlabs/lemonsqueezy-mcp

One click adds this to your local Yaw MCP config so it's available in every Yaw Terminal session. Or install manually below.

MCP server for the LemonSqueezy API. Manage your store, products, customers, subscriptions, discounts, license keys, and more from any MCP-compatible AI assistant.

Quick start

npx -y @yawlabs/lemonsqueezy-mcp@latest

Requires Node.js 22 or later (engines.node is >=22).

Or one-click install via Smithery:

npx -y @smithery/cli install @yawlabs/lemonsqueezy-mcp --client claude

Smithery prompts for your env vars (API key, optional guardrails) and writes the config into your client for you.

What it looks like

Once configured, you can ask your AI assistant store-management questions in plain English and it routes them through the MCP tools:

You:  How much did we make from the "Pro Annual" plan last month?
Claude: [calls ls_list_subscriptions, ls_get_variant, ls_list_subscription_invoices]
        Pro Annual brought in $14,280 across 84 active subscriptions in April.
        Three of those were upgrades from monthly; none churned.

You:  Refund order #LS-1234 in full.
Claude: [calls ls_get_order to fetch the total, then ls_refund_order with amount = total]
        Refunded $99.00 against order LS-1234. The customer's card will see the
        credit in 5-10 business days.

You:  Disable license key abc-123 for the customer who reported abuse.
Claude: [calls ls_list_license_keys to find the ID, then ls_update_license_key with disabled: true]
        License key disabled. Their existing activations will fail validation
        on the next check.

Guardrails (refund cap, rate limit, store allowlist) catch the obvious mistakes before they reach LemonSqueezy. See Configuration for the env vars that turn them on.

Setup

Set your LemonSqueezy API key as an environment variable:

export LEMONSQUEEZY_API_KEY="your-api-key"

Get your API key from your LemonSqueezy dashboard.

Docker

A multi-stage Dockerfile is included at the repo root. The runtime image is a single bundled file on node:22-alpine running as the non-root node user, with no port exposed (stdio transport).

docker build -t yawlabs/lemonsqueezy-mcp .
docker run --rm -i -e LEMONSQUEEZY_API_KEY="your-api-key" yawlabs/lemonsqueezy-mcp

A matching Containerfile is provided for Podman users. It is generated from Dockerfile via npm run gen:containerfile. release.sh runs npm run check:containerfile in step 1, so a release fails if the two have drifted. This repo has no CI, so nothing checks a pull request for drift: run it yourself after editing Dockerfile.

Tools (64)

Users

• ls_get_user — Get the authenticated user

Stores

• ls_get_store — Get a store by ID
• ls_list_stores — List all stores (not gated by LEMONSQUEEZY_ALLOWED_STORE_IDS: returns every store the API key can see)

Customers

• ls_get_customer — Get a customer by ID
• ls_list_customers — List customers (filter by store, email)
• ls_create_customer — Create a customer
• ls_update_customer — Update a customer

Prices

• ls_get_price — Get a price by ID
• ls_list_prices — List prices (filter by variant)

Both annotate every price record with effective_unit_price, the cents actually charged per unit, and effective_unit_price_note, which says where that number came from; unit_price_is_not_charged or unit_price_is_per_package is added where it applies. Read effective_unit_price rather than unit_price, which is vestigial on tiered (volume / graduated) pricing, or a variant's price. The subscription-item reads apply the same annotation to prices embedded via include=price.

Webhook sink (optional)

Bridge to a separate @yawlabs/lemonsqueezy-webhook-sink process so the agent can reconcile against webhooks that actually fired. Tools are always registered; if LEMONSQUEEZY_SINK_URL / LEMONSQUEEZY_SINK_ADMIN_TOKEN are unset, calls return a clear "not configured" error.
