Crosspay Skills

Agent Skills are self-contained guides that teach an AI agent how to perform a specific task well. Crosspay publishes skills so that Claude and other skill-aware agents can integrate, operate, and onboard Crosspay correctly, without you re-explaining the platform each time.

Available skills

Skill	Description
crosspay-integration	Integrate Crosspay into an app or backend. Covers the data model, client and backend API planes, store setup, API keys, and webhooks.
crosspay-billing-ops	Run live billing operations: check a customer’s access, list customers, and cancel Stripe or GoCardless subscriptions. Pairs with the MCP server.
crosspay-store-onboarding	Automate connecting a store (Google Play, Stripe, GoCardless, or Apple). Provisions credentials via `gcloud`, the Stripe API, or the GoCardless API, then connects to Crosspay. Includes a `gcloud` script.
crosspay-openapi	Author and maintain an LLM-optimized `openapi.json` so models can reliably call the Crosspay API.

Installation

From skills.sh

Crosspay skills are published on skills.sh, the community registry for Agent Skills. Search for “crosspay” and install with the platform’s one-click or CLI install for your client. This is the easiest way to stay on the latest version.

Manual installation

Each skill is a folder containing a SKILL.md file along with optional references/, scripts/, and assets/ directories. Copy the folder into your agent’s skills directory:

# Claude Code, user-level
cp -r crosspay-integration ~/.claude/skills/

# Claude Code, project-level
cp -r crosspay-integration .claude/skills/

The skill’s description field controls when the agent loads it. You do not invoke skills manually. The agent consults the description and loads the skill automatically when your task matches.

How skills and the MCP server work together

Skills and the MCP server are complementary:

Skills provide the knowledge: the Crosspay data model, the correct sequence of steps, the manual gaps in store onboarding, and security practices.
The MCP server provides the actions: callable tools to check entitlements, manage apps, and a crosspay_store_connection_guide tool that returns step-by-step instructions.

Together, they enable a seamless workflow. The agent reads the crosspay-store-onboarding skill to understand how to provision a store’s credentials, runs the bundled gcloud script, and guides you through the dashboard where you enter the secrets.
