Implementation Reference

• src/index.ts:375-380 (handler)

  The handler function that executes the cancel_order tool logic. It calls the API DELETE endpoint for the specified order_id and returns the result as JSON.

  async ({ order_id }) => {
    const data = await apiDelete<unknown>(`/orders/${order_id}`);
    return {
      content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }],
    };
  }

• src/index.ts:374-374 (schema)

  Zod schema definition for cancel_order input validation. Defines order_id as a required string parameter with description.

  { order_id: z.string().describe("UUID of the order to cancel") },

• src/index.ts:371-381 (registration)

  Registration of the cancel_order tool with the MCP server. Includes tool name, description, schema, and handler function.

  server.tool(
    "cancel_order",
    "Cancel an open order by its ID.",
    { order_id: z.string().describe("UUID of the order to cancel") },
    async ({ order_id }) => {
      const data = await apiDelete<unknown>(`/orders/${order_id}`);
      return {
        content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }],
      };
    }
  );

• src/index.ts:118-128 (helper)

  Helper function apiDelete that performs HTTP DELETE requests to the API. Used by the cancel_order handler to make the actual API call.

  async function apiDelete<T>(path: string): Promise<T> {
    const res = await fetch(`${API_BASE}${path}`, {
      method: "DELETE",
      headers: getAuthHeaders(),
    });
    if (!res.ok) {
      const text = await res.text();
      throw new Error(`API DELETE ${path} failed (${res.status}): ${text}`);
    }
    return res.json() as Promise<T>;
  }
