Shop ERP

The Marques Boxing MCP exposes these tools to active owner and staff callers. A teacher or automation caller does not receive the shop tools. Call tools/list to verify the current session’s tool names and input schemas.

These tools manage the internal shop. They do not register a canonical finance journal entry. See Expenses and income for that separate workflow. A customer can link to a student when requested. A standalone finance income entry does not require this link.

Use the input schema for the current tool to supply its idempotency and correlation fields. Read the stored record after a write. Preserve the same idempotency key when you retry the same operation. Do not treat a failed or timed-out response as proof that no write occurred.

Owner-only fixture cleanup tools form a separate operator surface. They require a preview and explicit confirmation. Use them only for controlled smoke fixtures. Preserve real gym and shop records.
